Building levels are used to measure the slope of horizontal and vertical surfaces. With the help of these tools, marking is made for the construction of various structures, assembling furniture, applying or laying finishing materials. Neither building nor renovation is complete without a level.
To decide on the choice of instrument, let's first understand what types of levels exist.
First of all, this is the water level. Its other name is the hydro level. It is used in cases where it is necessary to find irregularities in the location of horizontal surfaces, because. his work is based on the main feature of the water surface: always take the same position - horizontal.
The hydraulic level is a sleeve, the length of which can be from five centimeters to several meters, at the ends there are flasks with a printed microscale. Building levels of this type have both pluses and minuses.
The plus is their ease of operation and low price, and the minus is that to use suchtool is possible by working only with horizontal planes. It is not allowed to store it near heating appliances. The water in the sleeve must not have bubbles, otherwise the readings will be erroneous.
Most often, craftsmen use bubble-type building levels. Such a device consists of a housing in which flasks with liquid are located.
If there is only one flask in the level, then it determines the error of only horizontal planes, with two flasks - both horizontal and vertical. If there are three flasks, then the magnitude of the turning level is also determined by such a device. Usually the bubble levels are rectangular in shape. Their length can be from 20 centimeters to 2.5 meters, and telescopic models - up to four meters.
Often, beginners are interested in how long the building level should be. 2 meters or less is the optimal size.
The body of the level is usually made of polystyrene or light metals such as aluminum. The liquid in the flasks is alcohol.
Available for sale and a subspecies of levels of bubble type - magnetic. This is a bubble tool, only with magnetic inserts. Very handy if you're working with metal as it sticks easily to metal surfaces.
Did you find what you need in the store? And how to check the level of construction? It's very simple.
Place the instrument on a flat surface. This provision should be noted so that a little later on the sameplace to put the second tool to be checked. There are divisions on the level, so the bubble will most likely move to one of them. You have to remember which one. Turning the level, we put it in the old place, which we noted a little earlier. If the bubble “leaves” in the same direction it deviated last time, then the level works perfectly. If not, keep choosing.
Recently, building laser levels have appeared on the shelves of building markets. These are very accurate instruments, but they have a drawback - this is their cost. If accuracy is above all for you, such a device is what you need. Accuracy is ensured by a laser beam, the length of which can reach up to one hundred meters.
