The relevance and role of automatic monitoring systems for buildings-and-structures’ foundations sediments, deformations, technological equipment, etc. at preventing emergencies and elimination of man-made disasters constantly increases. In geodetic instrumentation in this field, the most easily automated method is hydrostatic leveling, where we use the characteristics of the liquids always settling at the same level in communicating vessels, and the distance is measured from the edge of the sensor’s vessel to the surface of the aqua. In order to simplify the process of this measurement, a new method was developed, where the level in all receptacle sensors rises evenly until it contacts the fixed electrodes instead of mechanical moving the contact electrode. The authors present the theoretical and experimental results of the hydrodynamic leveling system further improvement. In particular, it is proposed that instead of uniformly raising the leveling tank and creating a liquid rush under the influence of which a stationary movement is created, this pressure in relation to its level in the sensors is installed in a stationary tank in advance, equipping its solenoid valve, which opens when measurements are started.
