The Deltabar FMD72 is used to measure the level, volume or mass of liquids in pressurized tanks. The system compromises two sensor modules and one transmitter. One sensor module measures the hydrostatic pressure (high pressure) and the other one the head pressure (low pressure). The level (electronic differential pressure) is calculated in the transmitter using these two digital values.
