When Fluid Density Varies
IMV31 density-compensated level transmitter uses differential pressure, pressure and temperature measurements to compensate for liquid and vapor density changes. It can be used in open or closed tanks. The transmitter transmits a 4 to 20 mA output signal proportional to level and provides HART digital communications.
