The Deltabar FMD71 dP level transmitter from Endress+Hauser measures differential pressure without impulse lines and capillary tubes. The transmitter features two pressure sensor modules, each connected electronically 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 4-20 mA with HART as a standard two-wire loop-powered device. One sensor module measures the hydrostatic pressure (HP) and the other measures the head pressure (LP). 888/363-7377;
