Deltabar FMD71/72 is ideal for measuring the level, volume or mass of liquids in pressurised 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.
- Eliminates issues of traditional differential pressure measurements using impulse lines or capillaries and offers outstanding multivariable level measurement.
- Deltabar FMD71/72 offers a superior response rate (up to 10 times faster than conventional DP transmitters) and eliminates up to 95% of drift caused by ambient temperature changes.
- As the sensors are separate to the transmitter, you can locate the transmitter in areas safe and convenient for personnel, offering improved safety and better access
