WATER LEVEL APPARATUS
This Water Level Apparatus has four glass tubes, of different shapes and cross sectional area, projecting vertically from a common horizontal tube, made of borosilicate glass.
(Wikipedia excerpt: ..."A water level ...[Alfadolasticho]) is a siphon utilizing two or more parts of the liquid water surface to establish a local horizontal line or plane of reference. It is used to determine the apparent inclination of an object or surface and for matching water level elevations at locations that are too far apart for a spirit level to span.
The simplest water level is a section of clear tubing, partially filled with water. Water is easily procured for use, and easily discarded after use. The ends are held vertical, and the rest of the tubing lies on the ground or floor. The water level at each end of the tube will be at the same elevation, whether the two ends are adjacent or far apart, so a line between them will be horizontal at its midpoint and a shed base, building foundation or similar structure laid out using several such lines will be "horizontal" within building tolerances on any scale over which use of a water level is practicable.[1]
Water levels have been used for many years. The water level is lower-tech than the laser level, but it can be more accurate over long distances, and works without a sightline, such as around corners. To avoid error, all of the water should be at the same temperature. Other sources of error include difficulty reading due to meniscus...")
