Levels for the floor

For floor

— levels designed to work with the floor — screeds, laying coatings, etc. A common feature of such devices is a fairly wide base, which, in fact, allows you to put the device directly on the floor. But the specific design and features of the levels of this type may be different. So, devices of a characteristic layout are quite popular — with two vertical projections intersecting at an angle of 90 ° (some models provide two more projections directed in opposite directions from the main ones). Such a device can be used not only on the floor, but also on the walls: if you firmly attach it with its base to a particular surface, it will form two clearly perpendicular lines on it. In the case of the floor, this can be convenient, for example, when laying tiles.
Another common type of floor levels are devices designed to detect irregularities. For this, a line formed on the floor using a vertical projection is used. During operation, the level placed on the floor and aligned horizontally rotates around the vertical axis, and the line "scans" the floor; when it hits a ledge, it becomes uneven. Note that in the simplest models, such a “scanner” uses only one projection, but there is also a more advanced version — a line created by two projections at once. Such a pointer, when it hits an uneven floor, is divided into two separate lines — this is much more noticeable than the deviation when using a single projection.
Also note that floor devices sometimes also include models designed for preliminary marking of walls before the screed — namely, for drawing a strictly horizontal line indicating the maximum height of the fill. However, not only specialized devices can cope with such a task, but also most general-purpose levels — the main thing is that they can form a horizontal line at a small height from the floor (about 3-4 cm).
