Eliminating issues associated with traditional differential pressure measurements by doing away with impulse lines or capillaries, the Deltabar FMD71 level transmitter uses two pressure sensor modules, each connected to a single transmitter. Using a Ceraphire ceramic sensor in the pressure sensor modules, the transmitter calculates the differential pressure from both sensors and transmits the level, volume, or mass via 4 to 20 mA with HART as a standard two-wire loop-powered device. One sensor module measures the hydrostatic pressure and the other the head pressure. Each sensor sends a digital signal corresponding to temperature compensated measured pressure to the transmitter. Additionally, each sensor in the FMD71 system has 0.075% reference accuracy, maximum nominal pressure measurement of -15 to 600 psig, and a -40°F to 302°F process temperature capability.
