Electronic differential pressure Deltabar FMD71

Application 

The Deltabar FMD71 is an electronic differential pressure (dp) measurement system designed to monitor the pressure, level, volume, or mass of liquids in pressurized tanks or distillation columns/evaporators. It uses two sensors: the high-pressure (HP) sensor to measure hydrostatic pressure and the low-pressure (LP) sensor to gauge head pressure. By processing these two digital readings, the transmitter calculates the liquid level. This electronic dp system addresses and overcomes the challenges posed by conventional mechanical differential pressure systems.

Ideal for measuring differential pressure, level, volume, or mass of liquids in pressurized tanks and distillation columns/evaporators.
