Application and construction Modular electronic differential pressure transmitter APM-2 is applicable to hydrostatic measure of level in closed tanks, density or phase boundary. The measuring system consists of 3 separate modules – central unit and two absolute pressure transmitters. Level is calculated in central unit basing on measurement from two pressure transmitters. High pressure transmitter measures hydrostatic pressure of liquid in tank, low pressure transmitter measures pressure of gases above the liquid. Differential pressure is calculated in the central unit. With default...
