Endress + Hauser FMD71 Electronic differential pressure Deltabar - measurement pressure or level, volume or mass

ENDRESS + HAUSER FMD71 Level measurement Deltapilot

Endress + Hauser Deltabar FMD71 is a differential pressure system, used to measure the pressure or level, volume or mass of liquids in pressurized tanks or distillation columns/evaporators. The high pressure sensor (HP) measures the hydrostatic pressure. The low pressure sensor (LP) measures the head pressure.
Electronic differential pressure transmitter with ceramic sensor (Ceraphire) for level, volume or mass measurement in liquids.

Endress + Hauser FMD71 measuring principle:
