Abstract
Multipoint hydrostatic leveling system (HLS) is a long-term measuring instrument of the vertical displacement field of various objects. The HLS consist of necessary number of communicating measuring vessels filled with a liquid. Dynamic processes of liquid movement in this system depend on its geometric dimensions and liquid properties. This paper uses a dimensionless hydraulic model of liquid movement in hydrostatic leveling system with an arbitrary number of sensors. Numerical simulations of dynamic transients in the HLS containing 4 sensors and 1 reservoir are performed. The estimates of the stabilization time for various liquid properties and geometric dimensions of the level are carried out. The analysis of the results obtained allows one to select the type of fluid and the combination of geometric dimensions that provide the minimum possible value of the interval of fluid stabilization after a disturbance. These estimates are made for water, silicon fluids and ethylene glycol water solution.
