The electronic dp Deltabar FMD71 from Endress+Hauser is a differential pressure system that is utilized to quantify the pressure or level, volume or mass of liquids in distillation columns/evaporators or pressurized tanks.
The high-pressure sensor (HP) quantifies the hydrostatic pressure. The low-pressure sensor (LP) assesses the head pressure. The level is estimated in the transmitter with the help of two digital values. The electronic dp system removes problems of conventional differential pressure measurements.
