Abstract

Summary

Geodesy is always about accuracy, so all devices used in it or related fields have spirit bubble levels (cylindrical or round). They are needed for placing devices in the working area or for determining the position of the angle of inclination of some surface. The first concerns both opto-electronic and optomechanical devices. In some cases, it is more convenient to use the level in which the indicator body - the bubble - is located in the lower part of the ampoule. In particular, such a level can be used in compressed conditions during surveying or in construction to control the horizontality of the ceiling. Therefore, in this study, the task is to determine the requirements for the filling liquid of the level and for the liquid bubble, which should be heavier. Two pairs of substances that will give the desired result were also selected.
