The building level is a tool that reveals the slope of surfaces. Suitable for indoor and outdoor use.

How do they work

The algorithm of work of any of them comes down to the choice of the installation point and the place of level measurement. The rest of the possibilities depend on the specific type of instrument and can be combined.

The building level helps:

1. Determine the verticality or horizontalness of a given surface - in order to establish a further scope of work and its necessity.
2. Find out in which direction the tilt occurred, in some models its exact size is also available.
3. Set clear guidelines when marking surfaces - before installing frames or furniture.
4. Calculate the volume of materials - for this, the arithmetic average of the levels of different points on the same surface is applied.
5. Determine a single level in different rooms - often required when installing ceilings or windows.

In low-rise construction or apartment renovation, manual variations of the tool are often used. These are devices without complex electronics and do not require special skills. Professionals use several types at the same time.

Types and functions of building levels

Hydro levels

The functioning of this type of instrument is based on the laws of physics about communicating vessels. Structurally, hydrolevels are two flasks connected by a transparent tube.

Peculiarities:

• This is an accurate view of the levels, but it is important that the hose is not kinked and that you have good vision.
• Suitable for checking slopes in different rooms at the same time.
• As a rule, they require pair work.

To bring the device into working condition, it is enough to fill it with water so that the upper meniscus of the liquid reaches the middle of both flasks, and no air bubbles remain in the tube.

Bubble building levels

Regardless of the size and design features, the principle of the device is the same. At least two flasks are built into the level body, where small air bubbles "float" in the liquid. Focusing on them, they check if there is a slope of the planes.

Peculiarities:

• The liquid in most cases will be technical alcohol. Allows measurements with an accuracy of 1 mm / m - this is the industry standard.
• Hard acrylic air bubbles offer greater precision. Accuracy 0.5 mm / m.

Some of the models of bubble levels are equipped with flasks on a rotating base. This allows you to work with inclined planes. Profile shapes are in the form of a box, a trapezoid and with one measuring plane, cast Shark (shark). Part of the tool is equipped with end elements that prevent breakage in case of falls.

Laser building levels

The convenience of this equipment lies in its non-contact use and in a large area of ​​coverage with markings.

Peculiarities:

• The device pendulum is leveled after unlocking. It is advisable to set the plane of the base horizontally.
• Manufacturers offer an additional mounting tripod, but its dimensions are not enough for marking at a height. In this case, a bar is used, which is fixed between the floor and another horizontal surface. The platform on which the tool is installed moves along it.
• In bright light, the laser beam is not visible to the naked eye. To resolve the issue, glasses with glasses in the red color range are used.

Some of the laser levels produce static vertical and horizontal lines in a limited sector. The alternative, using a running point in a circle, allows you to make markings simultaneously from all sides.

Magnetic building levels

Magnetic levels are visually indistinguishable from bubble levels. The difference is noticeable only at the bottom ends. This option is equipped with magnets for easy handling of metal surfaces.

Peculiarities:

• Strip magnets are more commonly used in polymer levels, in combination with a V-notch for ease of handling on pipelines.
• Ceramic magnets or ferrites have been the industry standard in levels up until recent years.
• Rare Earth - Most aluminum models now come with this type of magnet. They are up to 10 times stronger than ceramic.

This type of level is more often used for work related to the installation of frames for drywall, as it is conveniently mounted on ceiling and rack profiles, leaving your hands free.

Optical building levels

An optical level or level is used in industrial facilities or in the construction of houses. The kit includes a special tripod, without which the use of the tool is unproductive. Installation comes down to mounting, focusing and centering.

Peculiarities:

• Centering is needed for point-to-point measurements. It is carried out using a plumb bob attached to the bottom of the tripod.
• Focusing - the telescope is aimed at the staff, the clarity is adjusted with the help of the adjusting screw. The eyepiece defines the reticle.

After setting, the survey of heights is performed. The captured data are summed up, their arithmetic mean is calculated. It will be the base mark from the instrument horizon.

Advantages

Each type has its own set of advantages:

• Hydro levels ... They support measurements in different rooms when the initial level is hidden by partitions or heavy structures. This functionality is not provided in other models.
• Bubble ... Easy to install and use, light weight and dimensions. Can be used to measure the level and simultaneously check the plane of the wall or floor.
• Magnetic ... Do not require additional fixation when working with metal. Enjoy the full benefits of bubble models.
• Laser ... Supports simultaneous vertical and horizontal measurements. Longer coverage than any handheld model. Automation of routine processes.
• Optical ... Applicability in open spaces, in the construction of roads and large facilities. Functionality, time and labor savings. When measuring at a distance, the accuracy is not degraded.

Problems

Disadvantages and inconveniences also depend on the type of instrument:

• Hydro. M is understandable and difficult to operate. The routine processes of filling, draining, unwinding and expelling bubbles are time-consuming. Not suitable for vertical surfaces.
• Bubble ... Often it gets lost, adjustment is often unavailable. Not suitable for working over long distances and areas. In adjacent rooms, the correct level cannot be determined.
• Magnetic ... The same disadvantages as the bubble. Magnets often protrude out of the plane of the rib - when measuring, fresh paint or putty can be damaged. Some models are less stable than bubble ones. Frequent breakdown of magnets is also a disadvantage.
• Laser ... Requires a flat surface. The pendulum often breaks down during transportation. The beam diameter increases with distance, which affects accuracy. Measurements of planes can only be carried out using additional accessories.
• Optic ... Adjustment is time consuming and requires skill. For domestic purposes, functionality is redundant - neither time costs nor costs are justified.

How to choose a building level

For most types of levels, accuracy will be the defining indicator, so it is important to check its correctness.

Bubble and magnetic

The same design also implies uniform methods for assessing the correctness of readings.

To check a horizontal flask, you need:

1. Place the tool on a flat surface.
2. Make two marks: at the end of the level and along - near the horizontal ampoule.
3. Remember the position of the air bubble.
4. Turn the spirit level by 180 ° and set in the same place in accordance with the previously made marks.
5. Check the position of the air bubble. Any differences in its position before and after flipping the level indicate an inaccuracy of the instrument.
6. Repeat the test, even if the readings are the same.

To check the vertical flask, set the level on a door frame or flat wall, further steps - by analogy with horizontal measurements.

Hydro

In this type of measuring instruments, there are no structural parts responsible for the accuracy of measurements, but there are nuances that should be considered when choosing:

• The length of the hose - you should not choose it in reserve, because the expulsion of air bubbles and the straightening of the tubes can turn this advantage into a problem.
• Pay attention to the tightness of the protective caps. Water should not be poured out - this will interfere with work.
• It is worth checking the integrity of the tube and the joints with the flasks.

An additional parameter is the flexibility of the hose, but it is difficult to assess it without experience with this type of level.

Laser

The choice of a laser level implies a comparison of a number of indicators:

• Measurement error - should not exceed 3 mm by 10 meters.
• Self-leveling - test multiple models. The preferred option is the pendulum of which aligns faster than in analogues.
• Range - marked as a radius or diameter. To avoid confusion, specify what type of distance is indicated. The laser is also responsible for the same parameter. A 532nM green beam will do most measurements.

Additionally, the integrity of the tool and the absence of mechanical damage are checked.

Optic

You need to choose a level taking into account the challenges and features of future use. They are divided into three classes: precision, basic and technical.

Peculiarities:

• An air damper is suitable for outdoor conditions, and operation in vibration mode requires the use of a magnetic version.
• To perform tasks in a confined space, the determining parameter should be the smallest sighting distance. For large objects, models with the maximum telescope magnification range are preferred.
• Leveling of the I or II class on construction sites is usually not required, but it should be borne in mind that only high-precision instruments can perform it.
• It is easier to prepare a tool with a compensator for work due to self-alignment of the sighting axis.

Which is better

The answers to these questions will help you choose the best type of tool for your current task.

What basic functions should the level perform?

• The functionality of the bubble level will cover all the problems of household tiling, but it is impossible for them to correctly measure the level of ceilings in different rooms.
• Laser - saves hours of work marking the walls for frames and wallpaper, but is not suitable for determining the correctness of the level of the planes.
• Optical - will support accurate calculations for laying routes, leveling surfaces, but it will not work to hang the shelves inside the kitchen cabinet with it.
• Hydro - will help to carry out a uniform marking of ceilings, but for the installation of wall frames, it is useless.

Where will it be used? Indoors, outdoors, or both?

• Most electronic models are not designed for outdoor use or in aggressive environments (rain, snow).
• Please note that in addition to the laser level, you will need a detector for outdoor use, as the rays will not be visible in daylight.

What is the required measurement accuracy?

Industrial lasers and levels have mechanical or digital counters, there is support for recording the angle of inclination with a step of 0.01%. For less accurate measurements, basic models of hand tools are selected.

Are you looking for additional features?

Professional-grade tools, accessories necessary for comfortable work. But the functionality of household and industrial models may not differ significantly.

How to use the building level

Features of use depend on the type of tool. There are no uniform operating methods.

How to use the hydro level

1. Carefully unfold the tubes and fill the instrument with clean running water through one of the flasks, while holding the other above. Try to fill non-stop to avoid unnecessary air gaps.
2. Check that the filling is correct - the tubes must be uniformly convex. Slightly clicks the remaining air bubbles to the flasks until they come out completely. If done correctly, the risks will rise to the same height when measured. This can be checked by placing the flasks close to each other.
3. Secure the caps.
4. Further, it is supposed to work together. One person holds the flask, and the second goes with a hose to a place or room, the level of which must be compared with the current one.
5. When both are in place, the caps are removed from the flasks. It is important to do everything at the same time and at approximately the same height - otherwise there will be overflows.
6. One person holds the flask against a predetermined mark, making sure to match the center of the water meniscus.
7. The partner gently raises or lowers the flask, thereby adjusting the level of water filling.
8. When everything is aligned, a level mark is made by the second participant.

Precautions: avoid kinking and mechanical damage to the hose.

How to use bubble and magnetic level

• Place the tool on the surface of the object to be checked for horizontal alignment.
• If the air bubble is to the right of the line, the object is tilted down to the left.
• If the bubble is to the left of the line, the object is tilted down to the right.

The vertical level is found by analogy.

Maintenance and care consists in the timely cleaning of the tool, especially after measurements on wet plaster surfaces.

Precautions are taken to protect the instrument from impacts and falls.

How to use the laser level

• Place the instrument on a tripod or flat surface.
• If the model is manually adjusted, check that the bubbles indicate a level. Otherwise, find the screws on the side and adjust them to the required correctness. Self-leveling - After installation, allow the tool to self-level, usually 30 seconds.
• Turn on the device. The device will emit a beam that is reflected on the surfaces. Depending on the type of laser level, it can be a point, a line, or multiple horizontal or vertical intersections.

If the device has not been used for a long time or has been dropped, calibration will be required. Installation on a rail or tripod is done using a clamp or clamps from the kit.

Precautionary measures:

• do not look at the beam itself, do not direct it at children or animals;
• do not use the tool in the rain;
• do not carry with an unlocked pendulum - many models warn about this with a sound signal or blinking of the laser.

How to use the optical level

Check the stability of the tripod before use. Tighten the mount with the tool. Make sure the leveling screws are not too tight on the base plate.

Alignment:

• While grasping the adjusting screws between your thumb and forefinger, turn them in opposite directions at the same time. While doing this, observe the movement in the graduated flask.
• The air bubble should be centered on the circular level window.
• Point centering is performed with a plumb line mounted on the tripod screw. Then the level is shifted over the head.
• Centering is complete when the plumb line is above the target point.

Focusing:

• Aim the telescope at a piece of paper or other light object.
• Twist the eyepiece until the desired sharpness appears - the sight should be clear.
• With the tube pointing at the supplied rail, adjust the focus using the knob.
• If the alignment is correct, the leveling rod scale and the crosshair of the target do not move one after the other.
• After focusing, hold the level on a specific target.

Use the focus knob to add sharpness.

Precautions are the same as for laser models, but extra careful handling of the lens is required.

Guarantee

The standard warranty excludes mechanical damage.

Bubble, magnetic and hydro - refer to hand tools. They rarely have a warranty over 12 months. Most manufacturers do not specify detailed conditions for these types of tools.

Laser - depending on the manufacturer and the category of the tool (household or professional), a warranty of 1 to 3 years is provided.

Optical - standard warranty period from one year. But the narrowness of the niche forces manufacturers to go for tricks. Some give a tool warranty for up to 25 years.

The warranty period can be counted from the date of purchase or shipment. In the second case, it is appropriate to clarify whether the instrument spent a lot of time in the warehouse.

Malfunctions and repairs

The weak links are different parts - their set depends on the type of tool.

Bubble and magnetic

The main problem is associated with the loss of correctness of measurements.

1. A flask with a bubble is knocked down - the readings will no longer be accurate, the error can reach several cm per meter. In budget models, flask adjustment is not provided - the tool is unusable with this malfunction. In other cases, tightening the screws or fixing clamps will return the level to the correct reading. During setup, a calibration is performed in the same way as when selecting a tool.
2. Profile bent - this happens when you hit and fall. The tool cannot be repaired, it will no longer give accurate readings.
3. Crack in the protective glass of the flask - in models of a collapsible type, the part is changed to an analogue. In this case, one-piece cast levels cannot be repaired.

Minor problems: breakage of protective pads and handles, falling off of magnets are corrected by replacing an obsolete part with a new one.

Hydro levels

Hydro-level faults are of three types:

1. Hose burst or cracked ... It occurs as a result of mechanical damage or freezing of a tool filled with water. As a temporary measure, you can seal it with a layer of nail polish and wrap it with electrical tape. Complete repair and replacement of the hose is often unprofitable - the costs are comparable to the purchase of a new hydraulic level.
2. Cracked flasks - temporary measures are similar to those presented in the previous paragraph, but instead of electrical tape, there must be transparent material in order to see the risks. Replacement may not be necessary in mild cases. In serious cases, it is imperative to change, since the defect will affect the accuracy of the instrument.
3. Broken or lost protective caps - the simplest case. They can be replaced with plastic soda lids.

Laser

The correction is often impossible to carry out on your own due to the need for a special tool.

1. Pendulum shift - the instrument does not work correctly, with deviations in horizontal and vertical measurements. This happens after the device has been dropped or moved with an unlocked pendulum. Reconstruction will require an offset correction. Such damage is not covered by the warranty.
2. The beam is off - the malfunction is caused by a break in the wiring or incorrect operation of the batteries. In the first case, you will need to remove the cover of the device and replace the flexible wiring going to the pendulum. In the second case, it is more often enough to open and clean the contacts or change the batteries. Both options lend themselves to self-repair.
3. Instability of readings - as a rule, it will be necessary to change the suspension bearing. The case is rare, but guaranteed in the absence of mechanical damage.
4. Buttons do not work - there are several breakdown options, of which only clogging of the contacts lends itself to self-repair. The keyboard may not work as a result of frequent use in dusty environments. Clogged contacts will need to be mechanically cleaned. The procedure is feasible in a domestic environment.

In difficult cases, a keyboard replacement will be required. When the coating is membrane, it will not be possible to repair the device without special skills.

Optical

Optical level problems are solved systemically or by replacing parts. Repair with an improvised tool is often inapplicable.

• Compensator sticking - to solve the problem, the standard calibration procedure is performed several times. In case of gross errors, service of the tool will be required.
• Lens or mirror cracked ... The purchase of a similar part is required. The optical lens can be replaced by yourself.
• The regulation is out of order - it will be necessary to adjust the device. The screw fasteners are loosened, the plate with the mesh is aligned. To do this, the horizontal thread is placed perpendicular to the axis of rotation of the tool, and the vertical one is set along a plumb line.

Problems in the operation of electronics, serious mechanical damage, repair of the platform or hauling of torsion bars will require the intervention of specialists.

Manufacturers

Manufacturers are represented in different price categories. The correlation between prices and quality is often insignificant.

Greetings, dear visitors! I've been pondering the topic for the last couple of days when I got an email from a reader asking him to talk about building levels. And I thought - a great idea. After all, where in the repair without a level?

The choice of levels is epic today. From the simplest water-based to digital with a built-in laser. What level and for what purposes is needed, as well as by what criteria to choose them - we will find out right now.

Building level: types

The simplest constructively is an ordinary water level, it is also a hydro level. It consists of two plastic usually cylindrical flasks with a scale, connected to each other by a flexible long hose. Its principle of operation is simple and should be clear to any high school student. It is based on a well-known physical phenomenon - the water level in communicating vessels is always the same.

With the help of such a device, we can easily mark two points located in the same horizontal plane at a maximum distance equal to the length of the hose. You just need to put marks opposite the boundaries of the water in the flasks.

Such a tool will be indispensable when building a country house, marking ceilings and floors during repairs and the like. Hose lengths of such levels are in the range of 7 - 25 meters, which is a lot. The cost of such a tool, of course, is low, in the region of 150 - 300 rubles.

It is more convenient to work with flasks not of a cylindrical shape, but with rectangular in cross-section - it is easier to apply them to the surface. The diameter of the tube - the larger, the faster the same level is established in both flasks. As a rule, hydrolevels have a diameter of 6 - 8 mm.

The next class of instruments is bubble levels or spirit levels. Most of them have a length of 40 - 250 cm. The horizontal and vertical lines in them are controlled by the position of an air bubble in alcohol sealed in special transparent flasks. Short spirit levels are needed when laying tiles, installing windows and sills ...

Long - for installing beacons, checking the vertical / horizontal planes and lines, all kinds of markings. Oddly enough at first glance, spirit levels can differ in many characteristics, which we will discuss in more detail in the next chapter.

Protractors and inclinometers are devices that allow you to measure and set the angles between the planes, and the slopes of the planes from the horizontal and vertical, respectively. Such devices may look different. Protractors are in the form of a flask in a quarter circle and in the form of two "rails" connected by a hinge, or whatever it is.

Basically, protractors and inclinometers are digital instruments, that is, they have an LCD display where the angle values ​​are displayed. The inclinometer is also often referred to as an electronic or digital level.

It seems to me that goniometers are needed mainly not by builders, but by carpenters. The inclinometers will be more useful to them. In finishing, the inclinometer will be in demand only, perhaps, for tiling works, and even then, more for control. Their highest accuracy (usually 0.05 degrees) does not leave the tiler a chance for even the smallest hack. And you will most likely get mad on the second or third tile))

A colleague of mine, a tiler, recently bought himself a Bosch digital inclinometer and has confirmed this. But, damn, how cool he is, this Bosch.

There are also various avant-garde types of building levels on sale. For example, trumpets. Moreover, they also come in different designs. There are devices in the form of "hairpins" that can be put on the pipe, there are ordinary bubble devices with a recess for a pipe on the body, and there are generally avant-garde masterpieces - "sticks" with five eyes, each of which is tuned to a certain slope - to make it easier to run the sewage system, you know whether.

Laser levels. I already have an article about them, so I will be brief. This is their most technologically advanced type (I mean self-leveling). High accuracy, ease of use, huge time savings when marking. Such devices are divided into two large classes: positional and rotary.

Positional ones do not have any moving mechanisms, as a rule, they give out a classic laser cross, or several points.

Rotary lasers give out one point, but due to the rotating base it moves quickly 360 degrees. Such devices are used, for example, by ceiling masters.

Bubble selection

Of course, the most common home repair tools are bubble ones. So what are the most important criteria when choosing a spirit level?

First you need to decide what kind of work you need it for. The length of the tool will depend on this. If for a tile, then you cannot do with one level, you will need at least two: short (40 or 60 cm) and long (200 cm). The short one is used constantly to check the level between adjacent tiles. Long - to control the entire surface of the cladding.

If you intend to assemble structures from gypsum plasterboard, plaster, fill the screed, you will definitely need a long spirit level, at least two meters.

The next most important criterion is form.

Levels are often found, in cross-section representing a rail. This is not the best choice - such a tool bends very much. Much more powerful than the box-type "stick". And if they have a stiffening rib inside, then it's generally excellent!

The next item is the flask arrangement.

An extremely important feature. In the store you can see levels, for example, with the following flasks:

In which case do you think the instrument readings will be more accurate? Of course, in the first one. The smaller the distance from the boundaries of the bubble to the divisions of the flask, the more accurately you can determine the deviation. Remember this. Also pay attention to the sensitivity of the bubble, it strongly depends on the radius of curvature of the bulb. It seems to the eye that the flask has the shape of a cylinder, but this is not entirely true, it is slightly curved, otherwise the slightest deviation from the horizon would "carry away" the bubble to the very edge of the flask.

One more thing can be added here. The flask for determining verticality is often inaccessible for a good view, because having attached the building level to the wall, we will not be able to look at the level readings parallel to it - the head is in the way. This means that we will not be able to objectively judge the readings of the device. But there are levels in which a special system of mirrors is built in, and the image of the bulb is "displayed" on the rear end of the level, which is extremely convenient. Such a system has, for example, the Israeli Kapro levels of the Plumbsite series.

The accuracy of the "sticks" for professional use is no worse than 0.5 mm per 1 meter of length; a simpler tool is also suitable for housework, with an error of 1 mm per 1 meter.

Processing of work areas. Ideally, they should be milled. This can be understood from the rough surface (s).

Having built-in magnets is also a very important addition to any level. Hang it on the profile and adjust it calmly. Still very useful "chips" of spirit levels are slots in the body for easy grip and rubberized pads, which often serve as shock absorbers in the event of a fall of the instrument.

Swivel and adjustable flasks are controversial advantages. Instruments for which manual adjustment is available instead of a “dead” mount are more likely to knock. Better to take once and for all sealed flasks. The main thing is to carefully check the tool in the store.

The verification procedure is quite simple. First put the level on the table or counter, look at the readings, remember. Then turn 180 degrees (but keep it in the same place!) And look again. If the position of the bubble is the same, the instrument is not lying. Do the same procedure for the vertical, just apply it to the wall.

In some spirit levels, the horizontal control flask is recessed in the middle. Personally, this decision seems inconvenient to me, and I do not advise you to purchase such a ***. The bulb should be on top, period.

Here's a nice video about bubble levels:

Well, here, he told everything he knew. Do not buy outright cheap, carefully examine the tool before buying. This concludes the article, thanks for your attention! And don't forget to subscribe to updates.

Asking the question of how to choose a building level, any person realizes the consequences of a wrong decision.

A common type of bubble level is the rectangular version, which is inexpensive.

After all, any, even the smallest deviation from a flat surface can lead to the most disastrous consequences up to a complete alteration of the just finished repair. Therefore, the question of how to choose a building level should be treated with great care, because this tool is of several different types, properties, purpose and price of which can vary significantly.

Currently, the market has a fairly wide range of these construction tools. One of the most common measuring instruments of this type is the bubble level. It consists of a body and a flask filled with liquid, in which an air bubble floats. This level is very simple and at the same time quite accurate and reliable.

What are the types of levels

The principle of operation of the water level.

Bubble levels. The most common type of this level is its rectangular modification. Its length varies widely and can be up to 2.5 meters. The minimum size is 20 cm. However, occasionally you can find telescopic devices, the length of which reaches 4 meters. Their flasks are made of impact-resistant transparent material. Alcohol is used as a filler.

Some of these tools are equipped with magnets, making them very easy to use on steel surfaces. There are also a variety of levels that are used when working with pipes: such tools are usually small in size and have a semicircular notch that runs along the body. Thanks to her, the device is well adhered to the surface of the pipe. These tools are not expensive, but versatility is not their strong point, so it is better to choose a different type of level.

Water levels. This type of measuring instrument, otherwise known as a hydro level, is well suited for measuring deviations of large horizontal surfaces. It consists of two containers filled with liquid, which are connected to each other by a hose. The main feature of these levels is that their length ranges from 5 to 25 meters, which makes them indispensable when working with extended surfaces and at the same time absolutely useless for use in an apartment.

The principle of the laser level.

They are sensitive to heat and should be kept away from heat sources. You also need to ensure that air bubbles do not get into the tanks when filling the containers with water, as this significantly affects the readings of this measuring device.

Laser levels. Measuring instruments of this type are among the most accurate and at the same time the most expensive. Their main advantages are their small size and large radius of action, which can reach several tens of meters. They are also best suited for measuring large and extended surfaces, since the laser beam emitted by this instrument can be turned into a plane. They also perform well when laying directions. For ease of use, such measuring devices are equipped with tripods and magnetic suction cups.

Top-end instruments have more than one laser beam. They can overlap, making measurements easier and more precise.

This device can definitely be called the best among all levels. It is versatile, accurate, compact and practical. It has only one drawback: its high price.

Choosing a level in the store: what to look for

The type of measuring device largely depends on how large-scale tasks will be solved with the help of it. After all, it is one thing when a level is chosen for frequent use in large-scale construction work, and quite another - when it is needed only in order to level the floor in an apartment.

There is no need to fall under the influence of the products of well-known brands and choose the most famous brand, because the main thing in any thing is its quality, and this indicator is often in no way connected with a big name.

How to choose a bubble type building level

Bubble level diagram.

First of all, you need to decide on what tasks you need this measuring tool for. If you are going to level the walls with it, then you need to choose the level of the maximum length, but if the question is posed much more modestly and you just need to attach a bookshelf, then the tool, accordingly, should also be smaller.

The air bubble itself should be clearly visible, and the marks on the level flask should be black and there should be several of them. These marks should be very close to each other, forming something like a scale.

After this stage of verification, you can proceed to the next one and test the accuracy of the device. If the purchase is carried out in a specialized store, then for sure he has special stands that are specially designed to test such measuring devices.

For the test, the device should be placed horizontally and precisely remember the location of the air bubble on the scale of the flask, then turn the level 180 degrees. If everything is in order with the device, then the bubble will not change its position relative to the scale.

After that, you need to check its work in the vertical plane. For this, an appropriate stand is selected, to which the device is applied. Then everything happens as in the previous case: the location of the bubble is remembered, then a 180-degree rotation follows. If the bubble remains in its place in this case, it means that the level is made with high quality and you can safely buy it.

In the absence of such a stand in the store, upon arrival home, you need to invite a person who has a level or laser level and with the help of these tools check the correct operation of the purchased one. If something does not suit you, then there is always the opportunity to return the purchased device back to the store.

What to look for when buying a laser level?

If you have made a choice in favor of a laser measuring device, then when buying, first of all, you should pay attention to its technical characteristics, the main of which are the measurement error and range. The accuracy of the laser level must be at least 3 mm for every 10 meters, and the range must be at least 20 meters.

Often, this device comes with special glasses that allow you to better see the laser beam.

In addition, these devices are equipped with two types of lasers, which differ in the color of the beam emitted by them. The most common emitters that give red color, but if possible, it is better to choose an instrument with a green beam, since this color is more noticeable and contrasting to the human eye. However, levels with a green laser are somewhat more expensive than their "red" counterparts.

It is worth taking a close look at what is included in the package of the device.

It is often very diverse and includes both many useful items and those that you can do without.

If, along with the purchase of a laser level, you are going to purchase some kind of addition to it, then be sure to consult with the sellers or with friends who understand such things, so that it does not happen that the purchased accessory does not fit your type of device.

Buying a level is a very important step, on which the quality of the upcoming repair directly depends.

How to choose a building level? And which one is better?

The final result of the work of a number of specialists in industrial areas depends on the accuracy of measuring instruments: a builder, a bricklayer, a carpenter, etc. The construction level of various modifications is a simple but obligatory tool for any serious team or individual craftsman, which allows to identify the accuracy of the location of horizontal and vertical surfaces. The history of the appearance of the first spirit level dates back to the second half of the 17th century, and the vertical plumb line is a well-known primitive prototype of later inventions.

Common classification for building levels:

• Bubble (spirit level) - with flasks installed in a rigid case, filled with liquid, and the presence of a floating air bubble in each flask;
• Laser level - with fast and clear marking of the laser beam point of the working surfaces;
• Water level (hydro level) - the principle of operation is based on Pascal's hydrostatic law and checks the conformity of the planes of the horizontal surfaces.

Despite all the obvious innovative advantages of the same laser level, skilled craftsmen never refuse to use a quality bubble level - this versatile, time-tested tool.

The main characteristics of the building level

• Measurement accuracy (from 0.3 mm / m, the longer the building level is and the heavier it is, the higher the accuracy of its readings);
• Impact resistance. As a rule, the levels have a hollow body, but with walls of sufficient thickness;
• Wide resistance to the slightest bending and torsion;
• Measuring flasks with high transparency and resistance to discoloration, haze, cracking and leakage when exposed to low and high temperatures, as well as ultraviolet rays.

Device

A rigid monolithic, most often rectangular case with a milled bottom edge is made of light and durable materials (aluminum, polystyrene, plastic, wood) with an anti-corrosion coating. In the case, depending on the required accuracy, a certain number of transparent sealed glass flasks (level eyes) with an air bubble floating in a colored alcohol-containing liquid are securely fixed:

• one flask - only for the horizontal rail (180 degrees);
• two - for horizontal (180 degrees) and vertical guides (90 degrees);
• three - for more complex work, with an additional third camera that controls the measurement of the angle of inclination (rigidly fixed at 45 degrees, or rotary - for measuring any angle of the controlled surface).

In order to minimize errors in angular vision, boundary lines are drawn on the surface of the measuring flasks - risks. Eyes for checking the position of the vertical plane surfaces and the angle of inclination have built-in mirrored reflectors for simultaneous control of the position of the bubbles.

Plastic plugs at the ends of the level protect the structure in case of accidental drops.

Some level manufacturers also provide additional conveniences: for example, a built-in magnifying lens for more comfortable eye control of the bubble, magnetic systems or fluorescent liquid of the flask for the possibility of continuing work at night.

The principle of operation of the bubble building level is simple: the measurement and adjustment of surfaces relative to the horizontal and vertical planes occurs due to the movement of the bubble inside a certain level eye. Correct adjustment will result in the bubble being exactly in the middle between the measuring risks of the flask.

Building level. Which is better?

Having made a decision to purchase a building level, it will not be superfluous to get acquainted with some recommendations for its choice:

1. Flask - must be securely attached to the body. When buying, it is worth abandoning the level in which the bulb is screwed on, because of which it may loosen over time. You should choose flasks made of polyacrylic, which is stronger than glass and more transparent than plastic.
2. The length of the level - it is necessary to take into account the type of work to be done, since the larger the working area, the longer the level should be chosen;
3. Defects - the building level is a measuring device, therefore, when buying a tool, you must make sure that there are no factory defects, as well as errors in the readings.

1. Body material - the instrument can be made of plastic, metal or wood. The most reliable and durable is, of course, the metal level, inside which the stiffeners are located
2. Marking - the best option is to place the control strips inside the bubble itself. The divisions applied to the surface of the flasks should be clear and located close to each other.

The spread in the cost of building levels is quite diverse. At the same time, it is not worth asking about the choice of more economic models, especially if it is necessary to use the tool repeatedly. If a thorough repair is to be carried out, then experts strongly recommend purchasing a professional tool. For it, a characteristic difference is the presence of a shock-resistant case with special rubber pads, which during operation are able to soften the shocks from falls, etc.

In operation, it proved itself better than others, the building level of the famous German brand "Stabila" has recommended. For such a tool, on average, you will have to pay from 700 to 1800 rubles. This measuring device is famous for such advantages as:

• high-quality and stable reading of indications (high degree of measurement accuracy);
• good ergonomic characteristics;
• precision in the geometry of the aluminum profile body.

In addition, magnetic building levels are also produced under this brand, which make it possible to work with electricity, and are equipped with special slots for marking for switches and sockets.

In addition to Stabila, another good option could be the building level of the Akula company. The good thing about the levels of this brand is that they are not afraid of falls and bumps. Also good models are produced by the firms "Ermak", "Bosch" or "Kapro". For example, the company "Kapro" constantly updates its models and often introduces the latest innovative solutions, releasing tools for household and professional type. Models of the German company "Bosch" are distinguished by their high quality. A similar tool with the Bosch models is also produced by the Russian company Condtrol, which is more affordable in terms of cost.

In the middle category of such instruments, it is worth highlighting the levels produced by the firms "Matrix", "Brigadier" and "Stayer", which are distinguished by special accuracy of measurements and an optimal ratio of cost to quality.

However, when buying a building grade, a well-known brand should not be a decisive aspect. The main thing is to decide on the type of future work and the frequency of using the tool.

180 degree method

You can check the accuracy of the level in the simplest way, called the 180 degree method:

1. It is necessary tightly, without gaps, to put the building level on a flat horizontal surface and remember the position of the bubble relative to the marks.
2. In the horizontal plane, turn the level 180 degrees and place it clearly on the same area.
3. In a qualitative and accurate level, the position of the bubble should remain the same.

The vertical accuracy of the readings can be checked in the same way.

Round bubble level

This type of building levels is designed to control only horizontal surfaces and is somewhat different from the usual levels in the design of the body with the same principle of operation. The round level is a sealed hemispherical capsule made of impact-resistant glass with a fixed flask, inside which the position of the bubble is determined by the bounding round line.

The scope of the circular bubble level is not only construction work and control of the degree of shrinkage of already rebuilt buildings. Levels of this kind are widely used in photography and video shooting to strictly adjust the position of the equipment tripod horizontally. It is very common to use circular levels and when installing commercial or control weights, as well as for constant monitoring of the stable horizontal position of stationary machines, industrial tools and even jewelry surfaces - for example, polishing wheels.

A circular bubble level often has the ability to locally attach to a controlled surface and is very low cost with high measurement accuracy. A knowledgeable person will appreciate this simple and necessary tool.

The ubiquitous use of levels

Whatever work you have to do (check the vertical and horizontal alignment of the walls, floor and ceiling surfaces; install a washing machine without distortions, hang a bookshelf or a picture) - the simplicity and ease of use of the bubble building level will help you do it quickly and with the highest quality. Even in the presence of a laser level or a plane builder that is more complex in execution and principle of operation, the building level that is unchanged in the arsenal of any master will not remain idle.

proinstrumentinfo.ru

Regular measurement and meticulous control are at the core of all areas of construction. If an ideal result is needed in decoration or renovation, marking and verification of the geometry of the structures is mandatory. A normal owner will not hang up a shelf or install a washing machine without measuring and control manipulations. They are performed using building levels used to comply with horizontal and vertical directions. These are fixtures and fittings that differ in complexity, cost, and purpose. The home craftsman should know which building level is better, what will come in handy or may not be needed on the farm.

The ancestors of building levels were a spirit level and a plumb line, which have been used by builders for marking and control since ancient times. The plumb line is used to determine the verticals, the spirit level - the contours.

The principle of operation of old uncomplicated devices is closely related to the law of universal gravitation. The most important element of the simplest devices is a weighty steel blank with a tapered tip. Under the influence of gravity, the metal part steadily tends downward, repeating the vertical line without the slightest error. Actually, a blank is a plumb line, which is banally suspended from a cord or fishing line, if you need to find or check the vertical direction.

In the spirit level, the plumb line is attached to the apex of an equilateral triangle or to the highest point of a structure resembling an inverted T letter. Its own weight makes the disc rush downward, thereby clearly marking the vertical line. The device is applied with the base to the surface to be tested. If the plumb line of the spirit level is not exactly in the middle, i.e. does not repeat the central axis, then the surface cannot be considered horizontal.,

All types of building levels used today in construction perform similar functions. They are used to mark structures before pouring the screed, leveling and plastering the walls, before installing plasterboard and suspended ceilings. Devices for marking and checking are necessary when manufactured, plumbing, window systems.

According to their functional purpose, representatives of the family of building levels are divided into two groups:

• Control devices. With their help, they check the quality of the masonry, the horizontality and verticality of the surfaces to be built, mounted systems, communications, devices. The control group includes bubble building levels, often referred to as spirit levels after their immediate predecessors.
• Devices used for marking. With their help, the position of points relative to the contours with verticals is determined, the contours of the created surfaces are drawn. This group includes the simplest water levels, plumb lines, and a more complex and high-precision category - laser devices.

There is no universal building level. For example, the bubble type is a very weak assistant in markup, although a number of models have rulers with a millimeter scale. Its purpose is to display deviations from the horizontal. There is only one working face, the other three are auxiliary: it makes no sense to apply them to any surfaces.

A primitive plumb line can be used for both stakeout and control, but only for vertical lines. It is best to mark the site with a laser level. True, the cost makes you think about the advisability of purchasing an expensive device for a single job.

The antediluvian water level is irreplaceable if you want to beat off points at the same height in rooms separated by partitions. Before purchasing these devices and devices, you should carefully think about the intensity of use and the rationality of costs. You need to weigh which of the tools you need to purchase and which is cheaper to rent.

In any case, you need to know exactly how to choose a building level, and clearly understand the scope of its application.

Bubble building levels

In the name of an uncomplicated control device, in addition to the "bubble" definition, on equal grounds, "alcohol" or "oil" can appear. In the people, depending on the shape of the body, they are called "box-shaped" or "rail". It is a bar or rail with mounted ampoules filled mainly with liquid, partly with air.

The case is most often metal, less often plastic, but there are still outdated wooden options. Among the materials of the case, the priority is metal, because polymers are not heavy enough and resistant to deformation, and wood products require increased attention, regular monitoring of readings and scrupulous care.

Regardless of the name, the principle of operation of bubble levels is the same. It is based on the difference in the specific gravity of liquid and gas, as well as the inability of substances with different states of aggregation to mix. Simply put, no matter what position the building level would take, a light air bubble will invariably end up at the top of a vessel slightly curved in the same direction. If it fits exactly in the middle, then the surface is perfectly horizontal.

The volume of the bubble does not change, this is prevented by a hermetically sealed ampoule-flask. It will not disintegrate into several components, because the liquid will incessantly push the air upward and group its scattered molecules into a single formation. To make sure, shake the tightly lidded jar of water. The small bubbles that have appeared in it will soon disappear, and the distance between the lid and the surface of the liquid will remain the same.

Functional classification

The number of built-in flasks determines the functionality of the building level model, because the devices:

• With one ampoule in the center of the working face to search for deviations in the horizontal direction;
• With two ampoules: a central flask for checking contours and a side flask for checking vertical planes and lines;
• With three ampoules, two of which, by analogy, are designed to check verticals and contours, and the third is used to control inclined lines and planes.

The third variety with three test flasks is universal. However, if the level is acquired only in order to carry out high-quality filling of the screed, or, there is no reasoned need for a third control device. It is in demand mainly in the construction of roofs and staircases.

The sealed flask is filled with an alcohol or oil solution, the freezing point of which is noticeably lower than that of ordinary water. Therefore, it became possible to work with a bubble building level at negative temperatures. Solutions are tinted for brightness of perception. They are distinguished by less fluidity than water, due to which the air bubble in the flask moves with agility sufficient for a calm visual fixation of its position.

Convenience and additions from manufacturers

The building level body is of the usual rectangular or T-section. The shape of the body does not affect the result of the readings, but it can be convenient or inconvenient for a particular human hand. Determining the ergonomics of a device is a purely personal matter, but it is advisable to carry out it before buying it on a crane. For the convenience test, you need to simply hold the instrument in your hands, compare several options.

Among the options offered by manufacturers to facilitate work with the building level:

• A magnifying lens that allows reading instrument readings without stress;
• The introduction of fluorescent components into the liquid for the ability to read indications in low light;
• Rubberized grip-type holes for improved usability;
• Magnetic inserts on the edge applied to the test surface for fixing to metal structures;
• Rulers that allow you to control geometric parameters simultaneously with checking verticals and horizontals.

Building level models are available with and without the listed add-ons. Still, the main convenience is rightfully recognized as the size of the ampoules, the pleasant brightness of the liquid and the clarity of the scale.

Those who want to buy a level with useful options should consider using them. They will certainly increase the price of the tool. Is it reasonable to overpay for something that is completely unnecessary to solve already set or only planned tasks?

Consideration of application prospects

Rack and pinion control devices are now available in electronic form, but the demand for conventional bubble control devices has not dropped at all. Simplicity wins over. After all, it has been proven by practice that the simpler the device, the more reliable and longer it serves the owner.

A simple device is easier to learn, it will not cause any difficulties in maintenance, it almost never requires expensive repairs.

To perform a variety of control operations, the levels are produced in lengths from 0.4 m to 2.5 m. Depending on the brand, the spread can be in both directions from the specified limits. Having pondered the question of which building level of the bubble group is better to choose for domestic needs, you need to focus on your own needs and real prospects.

It should be borne in mind that devices:

• Lengths from 2m and more are designed to control the planes of ceilings and walls, to check the quality of screeds, leveling with plaster;
• Lengths in the range of 1 - 2m are used to check the evenness of brickwork, geometric data of suspended and stretch ceilings;
• With a length in the range of 0.4 - 1 m, they are suitable for arranging window and door openings, for installing and hanging a variety of household appliances, for performing various finishing and repair procedures.

Do not forget that you need to take care of the storage location of the building level over 2m in length. Remember that the error for long devices is much less than that of short counterparts.

Noteworthy aspects

It was not in vain that the simplicity of the design inspired the sculptors of forgeries with vague thoughts about the possibility of the serial production of fakes. Checking documents for products before purchasing will save you from offensive oversights and from buying "left-handed" devices.

Products of domestic manufacturers must comply with the GOST 9416-83 protocol, devices from foreign manufacturers must comply with ISO 9001.

In addition to checking technical documents, the buyer of a bubble construction level must:

• Thoroughly examine the condition of the main elements of the device - ampoules with liquid;
• Decide on the size of the devices and the color of the liquid;
• Inspect the fasteners. There are models on sale, the flasks of which are fixed with adjusting screws. Whether they are needed or not is a moot point. According to experts, the levels should not be adjusted on your own. The result of the efforts of ignorant people is too dubious.
• Investigate the clarity of the application of the metric scale and divisions of the protractor, if there is an ampoule for controlling the angular directions;
• Test ergonomics, i.e. hold in hands;
• Examine the condition of the hull.
• Check the accuracy of the readings.

Most of the specialty stores have flawlessly horizontal stands.

Suppose you are buying a level from a recently opened retail outlet or online store. In such situations, the accuracy of the readings of the monitoring device is checked as follows:

• Let's find a horizontal platform on which the tested level can fit freely. Without instrumental definitions, it should appear practically flat;
• We apply the tool to the surface. With a marker or pencil, outline the contour of the corners so that the level can be put back in the same place.
• We fix and remember the position of the bubble. We note how far he deviated from the risks.
• Turn the level over 180º and set it according to the marks made earlier.
• We fix the position of the bubble. If he took a similar position, there was no doubt about the accuracy of the device. If not, check a couple more devices.

The ampoule responsible for the verticals is checked by an identical method, but on a vertical plane. There is also a popular method of applying two spirit levels to each other with working edges. The position of the bubbles according to this method must be the same, otherwise one of the devices is blatantly lying.

There are also tips according to which, to check the rack and pinion device, a horizontal line is bounced off with a water level or a laser level, the principle of operation of which should also be studied.

The simplest water level

The device consists of two flasks of equal volume, interconnected by a flexible thin hose. Used in laying out horizontal lines if you want to stake out in different rooms or at large distances. Those. where the use of a laser level is impossible, unprofitable or meaningless.

The principle of operation of an elementary device is based on the law of communicating vessels. The water level in both communicating vessels will always be at the same absolute mark, for fixing which there are risks on the flasks.

The use of a water device allows you to correctly beat off the horizontal lines regardless of the real position of the surfaces of the floor, ceiling, parapet, etc. No digital apparatus has yet been able to replace it. Note that the reference horizon is bounced off by the water level, from which the heights indicated by the project are then deposited. With its help, they do not directly mark future planes formed by a suspended ceiling, logs or, installation points for plumbing fixtures, etc.

For marking with a water level, we will invite an assistant, we will act like this:

• On the wall, mark an arbitrary point at a distance from the floor, convenient for making markings;
• We apply one of the flasks to a point, fix and remember at what mark the water level is established;
• We send the assistant to the desired point. Moving his flask up / down along the wall, he must find a position in which the water level is established at an equivalent mark.

Weighty advantages of the device: low cost, simple operation and accuracy. Cons: inability to break down at negative temperatures, limited use, the need to wait until the level is established in both flasks.

Advanced lasers

Buying a laser level for use in a domestic environment is considered unprofitable. Why do you need an expensive device at all, if the marking can be done using a water level and a ruler? However, for the owners who have decided to seriously equip their country estates, the laser device will certainly come in handy. It will help to lay out open areas and closed spaces, ensure the accuracy of vertical and horizontal lines, and, if necessary, mark entire planes in the processed space.

In construction, a variety of models of laser devices are used: from compact pocket devices with a built-in laser pointer to highly complex multiprism devices that allow marking in three mutually perpendicular planes.

The miniature version is ideal for everyday household needs and cosmetic repairs. To perform in-depth redevelopment, cardinal leveling of surfaces, laying pipelines, it is advisable to acquire a serious laser level installed in a stationary position on a tripod or on a wall bracket.

Most of the lasers used in construction only hit the vertical and horizontal lines. Some of the newer modifications are equipped with the function of staking out inclined lines, which are required for the construction of stairs, for example. Instructions for use are simple, manufacturers attach a detailed description to the device. The optimal color of the laser beam is green, because it does not irritate the eyes, and is also perfectly readable in brightly lit rooms and outdoors in sunny weather.

Videos with a detailed explanation of how to correctly choose the desired device will help to finally clarify the issue.

Overview of Bubble Variety Devices:

Bubble level accuracy check:

Disassembly of compact laser levels:

Let's summarize. A rack-and-pinion level with bubble "sensors" is not used for marking. With its help, the horizon and verticals of the structures being built and restored are checked. The breakdown of the premises and the construction site is performed with laser devices. If the laser is not available at a cost, the marking is done with a good old plumb line paired with a water level. There is no universal device, each of them performs its own functions.

When buying a building level, you need to carefully study it. But to learn it, you need to know what to learn.

First of all, you need to pay attention to how the flask with the bubble is located. It should be absolutely flat without any bends. If there is even the slightest error, then during construction it can greatly interfere.

Secondly, if you buy a level in the store, you need to test it right away. Bring it to the wall, floor. You need to make sure the level is showing correctly.

I will tell you about one good way how not to be mistaken when choosing a building level, which I always use myself. It is necessary to put it on some flat surface and mark on this surface with a marker (pen, pencil) marks how it stands.

Then you need to turn it 180 degrees and put it in the same positions according to the marked marks. If the bubble in the flask is in the same position as it was before, then the level is in good order.

It is necessary to do the same for the vertical level. In the same way, we put it against the wall, the bubble should be in the middle. Turn over and put in the same positions. If the bubble is in the same place, then the instrument is working properly.

It is not worth saving on construction tools, since most of the cheap levels bend easily, which will be inconvenient when working.

1. It is necessary to choose a fairly weighty level, it should not consist of some kind of light material.
2. The bubble should move smoothly when tilted without jerks and delays.
3. There should be no foreign objects or debris in the vial.
4. The body must be thick enough.
5. The walls should be about 3mm.
6. If you are working at height, then you need to buy a level with a magnetic stripe. Since it will be very convenient to magnet it to the surface and you will have free hands.

It is necessary to treat the level quite carefully, it is afraid of falls, since the bubble may deviate.

A bubble level is necessary for small and small jobs. For larger-scale works, it is necessary to use a laser level.

With a laser level, everything is much easier. You put it on a tripod, and then either adjust it manually using a bubble level, or turn on self-leveling, in which it will adjust itself.

With a laser level, you can do the same things, but much faster. You just turn it on, set it up with one button and that's it, the level is ready.

Some laser levels have lasers that shine 360 ​​degrees. That is, you just put it in the center of the room and that's it.

How to adjust it?

There are levels that allow for adjustment. The sensing element (flask with liquid) in such levels is fixed with a bolt.

If the bolt is loosened, then the sensor can be turned, thereby adjusting the level. Customization is usually done in one of two ways. Either we simply move the flask with our hands (such an adjustment is less accurate), or an adjusting bolt is provided, by turning which, we adjust the position of the flask (more precise adjustment is possible). Not all hydraulic levels are adjustable. There are those in which the flask is glued. If such a tool is defective, it must be thrown away.

It is not a problem to adjust the level if you have a strictly horizontal surface.

But a vicious circle ensues. To repair a building level, you need a horizontal surface, and to find a horizontal surface, you need a serviceable level. Let's get a horizontal surface using a broken spirit level.

Let's cut a stack of small pieces of paper, like a newspaper. Let's find a stable (stationary) approximately horizontal surface. Let's put our faulty level on it.

Put several pieces of paper under one end of the level so that it shows horizontality. Let's remember how much paper was put in this (first) time. Turn the level horizontally so that its right end is now on the left, and the left end is on the right. If the level is serviceable, then it will continue to show horizontality, since the serviceable level shows the horizon, and the horizon is one, which is from right to left, which is from left to right. If the level needs adjustment, then as a result of turning the air bubble in the flask will shift, the level will show that it is no longer horizontal.

Put a few more pieces of paper under one of the ends of the level so that it again begins to show horizontal.

You may need to re-insert the paper at the same end as last time, perhaps at a different end. At the same time, we count each enclosed piece. Now let's remove exactly half of the pieces of paper that were placed in the second step.

If there were an odd number, then round off. Congratulations, we've got the true horizon.

But the level shows deviation. We release the fixing screw, turn the flask so that it shows horizontal position, tighten the fixing screw. Configuration completed successfully.

The vertical flask is adjusted in exactly the same way. But to do it, you need an assistant, since it is performed on an approximately vertical wall.

And on such a wall, pieces of paper and a level by themselves will not hold. The assistant will have to hold them.

From a mathematical point of view, the proposed method is not entirely accurate, but for construction purposes the error is acceptable.

Unfortunately, errors are periodically encountered in articles, they are corrected, articles are supplemented, developed, new ones are being prepared.

Which level should i choose?

How to choose a construction level? Is a frequently asked question about every newbie or ordinary citizen who has decided to secure his own hands on his own.

The spectrum of these instruments in the modern world is very diverse. The market today has many different types of levels, from the simple cheap to the most advanced professional.

But we need an accurate and reliable level. First, let's find out what the differences are and take each one into account.

Water level (water level)

Builders often refer to this as the water level. It is used when it is necessary to detect deviations from horizontal surfaces. The principle of its operation is based on the properties of water to establish a horizontal position in accordance with the law of communication vessels.

The water level is a tube up to 25 m long, at the ends of which there are bulbs with a scale.

Water is poured onto the surface of the water, resulting in noticeable weight.

• Prostate.
• Low cost (about 100-200 rubles).
• Ability to work with very large surfaces.

• When the level is filled with water, it is necessary to control the absence of air bubbles, otherwise the measurement error will be large.
• Do not use tools with heating devices.
• Only for horizontal surfaces it is impossible to work with vertical surfaces.

Bubble Construction Level

This is the most common one.

It consists of a body in which several small glass flasks are closed with liquid. Depending on the number of lamps, it can be determined by horizontal accuracy (one bulb), horizontal and vertical (containers), horizontal, vertical and inclined (three bulbs) surfaces.

The most accurate bubble level is, of course, one with three flasks. Most often, the bubble has a rectangular level with a size of 200 to 2500 mm.

The choice of length depends on the dimensions and the accuracy of the application to the surface.

The body of the level is made of lightweight and strong materials such as aluminum, plastic, wood or polystyrene, and most often alcohol is poured into flasks. Some bubble levels are made with magnetic plates that help to process metal pieces. They are also called magnetic levels. Sometimes the mark refers to one of the two levels of the bubble, for use as a ruler.

How to choose the type of building level bubble level?

Of course, it's best to focus on a good brand that makes professional tools.

For example, the level of construction of the German company Stabila (costs about 600-1600 rubles). This company manufactures magnetic levels, as well as various devices that allow you to work with an electrician (there are special slots for marking a switch or socket).

For full-scale measurements of 600-700mm level, you do not need to buy a two-level level.

In addition to Stabile, you can also opt for Shark tools.

This indicator is not scary to fall or hit, it will not suffer. You can still buy from the products: Bosch, Kapro or Ermak.

How do I check the level of a building?

You must place the level on a flat surface.

For example, it could be a desktop or a sales window. Remember your position, then put the second level in the same place. A vial from one bulb will likely slide to the side. If this happens, memorize the position of the bubble according to the sections of the lamp.

Rotate the tool 180 degrees and insert it to its original position.

If the air bubble moves to the same position, the level is displayed correctly. If this does not happen, change the level to another and try a new one. You can also check any vertical water level.

• Availability.
• Prevalence.
• Easy to operate.
• Some allow you to measure at an angle.

Pipe level

This type of level is also a bubble, but it is slightly different.

They have less weight, some may lose weight. The pipe level is designed to work with pipes and profiles, which are most often equipped with additional devices for fastening pipes.

• Availability.
• Prevalence.
• Simplicity and practicality of work.

• There is a small chance of error.

Laser levels

Laser levels are the most accurate of all models presented.

These modern tools are very reliable and at the same time very expensive. Their prices range from 2,000 to 18,000 rubles, depending on the manufacturer and many functions.

It is a very convenient and compact tool with high technical capabilities. The advantage is that the laser beam reaches a length of up to 100 meters. If you are planning to purchase this type of level, it is better to choose reliable brands such as Bosch or GrossLaser.

• Easy to operate.
• Very high precision.
• Compactness.

How do I set and use a building level?

To properly control the level of a building, it is necessary to adjust it correctly.

To do this, read the instructions. This is an individuality for each brand and model, it contains all the necessary rules and recommendations. Some have bike tuning settings, others, if it is an electronic level, most likely the tuning will be automatic, you will only need to select the support system.

It is very important to follow the instructions, as even a new level has a certain error. Adjust the level correctly.

To correctly adjust the hydraulic level, it is necessary to fill with water and observe the absence of air in the thin pipes up to the zero mark of the bottles.

After that, the lamp labels should be merged. If it doesn't, there are air bubbles or the tube is being transported somewhere. Do not fill the water level with ice or suppressant water, the liquid should be at room temperature. This facilitates an even distribution of heat throughout the entire level contour, ensuring maximum measurement accuracy.

The bladder level requires careful treatment.

Building class

This is a very delicate instrument. Do not press firmly on it, do not look or smear it. It is easy enough to apply it effortlessly to the surface, and if the surface is perfect, the air bubble will obviously be in the middle of the measuring marks.

Try to check the accuracy of the level measurement regularly as it can be misleading.

Building levels: types, selection and purpose

The level is an indispensable tool when performing construction and installation work. It is necessary for the correct installation of doors, windows, laying bricks and tiles, checking the verticality of the walls, the horizontalness of the floors. With its help, the installation of modern household appliances, communications is carried out.

Choosing the right measuring tool significantly improves the quality of your work and saves you time.

By design, there are five main types of building levels: bubble, electronic, pipe, hydraulic, laser. Below we will look at each of them in more detail.

Five types of building levels

Bubble levels received the greatest distribution due to their simplicity, availability and versatility.

They are called so because their sensitive element is an air bubble floating in an ampoule. The measurement error of these devices is 0.5 ÷ 1 mm / m. Domestic models are produced in accordance with GOST 9416-83, which describes the technical conditions for their manufacture. The tool body is a hollow box-type structure with stiffening ribs. It can be from 30 cm to several meters in length.

To reduce the mass, the device is made of aluminum alloys. Ampoules with air are closed with protective glass. At the base of the case, as a rule, there is a millimeter scale for measurements.

For working with metal structures, magnetic bubble levels are perfect.

Their distinctive feature is the presence of built-in magnets, which allow the tool to be fixed vertically on metal parts. For bricklayers, there are models with a reinforced cast body.

If you have plastering work ahead, pay attention to the rules with the level. They combine two devices at the same time.

Electronic levels with a protractor refer to a professional measuring instrument.

They have multiple vials for assessing the vertical and horizontal position of building structures. However, unlike conventional levels, such devices have a number of additional features.

One of the main features is the digital display, which clearly displays the deviation in degrees.

At the same time, the accuracy of the data provided is high - up to 0.1⁰. It is possible to record the measured slopes. An audible indication is provided, which signals the achievement of 0⁰ and 90⁰.

Checking the accuracy of the electronic level is simple and does not take much time. To do this, put the device on a flat surface and take readings.

Turning the level 180 degrees, see the new values. If the difference in readings is more than 0.2⁰, the device needs to be calibrated.

Pipe level designed to check the horizontal and vertical alignment of water, gas, sewer pipes.

In general, it is convenient to use it to work with beams, round profiles in various building structures. The main features of this tool are the V-shape of the body and the presence of magnets.

Thanks to this, the device can be easily installed on a metal pipe or support.

The pipe level, like the bubble level, is equipped with several flasks with an alcoholic liquid.

In each of them, an air bubble floats, according to the location of which the deviation from the given direction is determined.

Hydro level It is used to apply precise horizontal markings on objects that are distant from each other. With its help, the floor level is beaten off, the foundation is installed, the brick is laid, and various building structures are installed in the same plane.

The hydrostatic level consists of two vessels connected by a transparent tube.

Before work, the system is filled with water so that it takes up approximately 2/3 of the volume of the flasks. At the same time, make sure that the liquid inside the tube does not contain air bubbles. They must be removed, otherwise the measurements will be inaccurate. Bends and breaks of the tube are not allowed: water should flow freely from one vessel to another.

To check the accuracy of the instrument, the flasks are aligned with each other. It is necessary that they have a common boundary of the liquid.

The industry produces hydrostatic levels from 5 to 25 m long. The measurement error of these devices is 2 ÷ 3 mm. It is recommended to make markings from one base mark. This allows for maximum accuracy.

Laser building levels(levels) belong to the group of professional measuring instruments.

Despite the relatively high cost compared to other solutions, they provide their owner with a number of advantages. First of all, it is high accuracy of marking. The permissible deviation is only 0.1 ÷ 1 mm / m, depending on the class of the device. The technical capabilities of linear laser levels allow them to build horizontal, vertical, and inclined planes at a distance of up to several tens of meters from the installation site.

For home use, this is more than enough. Rotating laser levels, due to the rotation of the emitter, project beams around the entire perimeter of the room, that is, they cover the entire space around them.

What construction work is carried out using laser levels:

• leveling walls or floors;
• installation of attachments;
• pasting walls with wallpaper;
• installation of stretch ceilings;
• facing of premises with tiles;
• installation of partitions, etc.

How to choose a building level

To carry out repairs efficiently, you should choose a good measuring tool even before starting work.

There are now a wide variety of building levels. They differ from each other in purpose, technical characteristics, workmanship and price.

What is your challenge ?! If you need an inexpensive, versatile tool for all occasions, you should pay attention to bubble levels.

They are comfortable, unpretentious, and most importantly, they have good accuracy. Their capabilities are sufficient to lay tiles evenly, install windows, doors or furniture. The length of the universal level is 60 ÷ 80 cm.

Electronic levels with a protractor and a magnetic system are suitable for those who decide to take up repairs seriously.

They have advanced features. First of all, this is a visual presentation of data on an electronic display with an accurate indication of deviations in degrees, percent or millimeters. Other distinguishing features are high accuracy, recording function, and the ability to electronically calibrate.

Whether you need to align beams, poles, water or gas pipes vertically and horizontally, take full advantage of pipe levels.

Their indisputable advantage is the ability to accurately center on these elements of building structures.

The water level will be useful when installing a floor screed, installing suspended ceilings, and arranging a foundation. It is useful for marking places for sockets, which will look aesthetically pleasing, being at the same height.

How to choose a bubble building level

With the water level, you can make accurate horizontal markings for adjacent rooms, between which there is no line of sight. This is one of its main advantages. This tool has a low cost, easy to operate. Its length varies from 5 to 25 meters, which is quite enough for domestic use.

The laser level will be an excellent choice for those who have a large amount of construction work.

It will significantly save time, while ensuring high accuracy of constructions of both horizontal and vertical planes. This is a good tool for cutting the floor level, marking walls for finishing work, installing furniture and communications.

There are three main types of laser levels: point, linear, rotational. As the name suggests, they are used to draw points, lines, and markings around the entire perimeter of the room at the same time.

Before starting work, the lasers must be leveled with the built-in bubble level.

Some models have an additional function of self-leveling within 2 ÷ 4 degrees. The price of professional laser levels is quite high, but there are affordable options for home use.

What to look for when choosing

Among the large number of manufacturers present on the measuring instrument market, there are those who have already managed to gain an excellent reputation in our country and abroad.

In good standing, builders have bubble levels, as well as electronic levels Stabila and Kapro. Known for their quality Bosch laser levels. However, it is best to rely on your own experience in order to purchase a thing with the necessary set of functions for a reasonable price.

The main selection criteria: technical characteristics, equipment, build quality and materials.

When purchasing a bubble level, it is necessary to inspect its appearance. Is there any visible damage ?! What is the quality of the materials, is it neatly assembled ?! Particular attention should be paid to ampoules with liquid.

They must be firmly embedded in the enclosure.

Place your chosen level on a flat, horizontal surface. It should fit snugly with its base without gaps. Remember the position of the air bubble in the upper ampoule.

Then turn the device 180⁰ clockwise or counterclockwise and put it in the same place. If the bubble has shifted from its starting position, this level cannot be trusted.

Similarly, you can check the vertical accuracy of the readings.

Possible difficulties with the level

Those who are going to make major repairs in an apartment will inevitably have a question about how to beat off the floor level so that it is ideal.

But for this, you must first determine how large the error is and understand how many materials and elements you need to purchase. Fortunately, the modern market offers many options, thanks to which it is possible to carry out alignment work with high quality and without any problems.

Methods and materials for measuring floor level

Each owner of an apartment or house independently chooses a scheme according to which the surface of the lower part of the room will be transformed.

The question of how to set the floor level takes on special significance in the case of:

• If the surface was previously leveled, but surplus raw materials remained on it and were not removed;
• If mistakes were made during construction and the surface was initially uneven;
• If the floor level in a private house is not sufficient for the introduction of a new coating;
• If the house or apartment is old and the surface has been damaged due to chemicals or the influence of external factors (flooding, fungi, dampness).

In any of these situations, you can fully determine how to check the floor level to transform the premises of an apartment or house to the fullest.

Based on the photo of the future repair of the space, it is necessary to conclude how much the level of the lower surface of the room needs to be raised.

There are various options for how to measure the floor level, the main ones are:

• Level measurement using a hydro level (water level);
• Measurement of the error in the flatness of the surface using a laser (read also: "How to check the flatness of the floor: how to check in practice");
• And also, measurement with a level, this option is used mostly by professionals.

Each of these options is suitable for its implementation.

The hosts can choose the appropriate one based on:

• Device pricing policy;
• Skills and experience;
• The technical side of the issue.

Hydro level

This level is a structure consisting of:

• Rubber tube;
• Two containers at both ends of the product.

When working with such a device, it is necessary to act in pairs and step by step. As a rule, this method is most often applicable, both among experienced builders and repairmen, and among beginners.

Step-by-step actions when asked how to display the floor level:

1. First you need to pour liquid into a transparent rubber tube, usually water is poured. The tube should be filled as much as it is planned to raise the floor level;
2. Then one of the participants in the repair work raises his end of the tube to the required height and, where the water stops, puts a mark on the surface of the wall;
3. How to determine the level of the floor will become clear when the second participant in the renovation reincarnations brings the tube to the other end of the room.

   It is necessary to wait a couple of seconds for the liquid to fully equalize in the vessel. After that, also put marks at the level where the water stopped in the tube;

4. The same manipulations can be performed with all other sides of the wall;
5. After the marks, you can lower the level a little if it turns out to be too high.

   To do this, you need a special meter. In this case, it is necessary to lower the level of the mark on both sides by the same number of centimeters so that the flooring does not turn out to be too high.

• Water does not flow through the hydraulic level tube... In this case, the instrument should be rinsed, perhaps there are some stagnant specks, due to which the liquid does not move through the vessel. You can also purge the water level so that unnecessary objects come out of it, which interfere with the normal operation of the device.
• The water is not on the same level.

  Such a nuisance can appear due to the formation of air bubbles. You can get rid of them by knocking on the water level tube or by re-entering water under high pressure.

Laser level (Leveling level)

Difficulties in the question of how to use the laser level to level the floor should not arise.

The process of using this method to determine the height of a surface is very simple.

The set for this equipment includes:

• Installation, emitting laser beams;
• Tripod (attachment);
• A stand thanks to which you can vary the height of the device.

Having understood the scheme of how to check the floor level with a laser level, the work process will take very little time and it is possible to perform this function even singly.

Step-by-step instructions on how to beat off the floor level with a laser level:

1. First of all, it is necessary to install the device. Depending on the cost, and therefore the quality of the tool, the installation process may be different. In budget models of the product, the equipment will need to be directed to each wall in turn.

   The best building levels according to user reviews

   In laser leveling systems, the illumination of laser drawings is applied to the entire area of ​​the room;

2. The second step is to draw a laser-drawn line on the wall.

   This function can be performed with a special upholstery cord or with a ruler and pencil.

3. After that, you can start the process of leveling the surface of the flooring.

Possible difficulties with the level

Determining the level of the floor with a laser (leveling) installation, it is extremely difficult to make a mistake.

However, errors are possible in the case of:

• If the edges of the laser directions are not evenly aligned;
• If, when transferring boundaries to the surface of the wall, the master or landlord of the apartment of the house incorrectly applied the dotted lines;
• If the level is set too low or high.

Conclusion

When choosing any of the options for measuring the level of the floor surface, the result will be accurate.

The only difference between these two measuring devices is the level of complexity in use:

• The laser system is very easy to use and with it the work is reduced to minimal actions on the part of the employee.

  But the cost of this device is quite high, from 5,000 to 20,000 Russian rubles.

• The hydro level also allows you to clearly define the height of the surface. This device requires a lot of effort on the part of the participants to repair. But you can even make this installation yourself, from improvised means, which can always be found in the storage room or in the garage.

Having carefully studied all the details and nuances of using floor surface level meters, you can fully and ideally carry out the process of leveling the lower part of the room.
