Application Area
The Prosonic FMU40 sensor is designed for non-contact level measurement of liquids, pastes, bulk materials, as well as flow measurement in open channels and weirs. The two-wire or four-wire compact transmitter can be used in tanks, agitators, storage facilities and conveyor belts. For convenient diagnostics, the echo curve is displayed on the screen. The linearization function (up to 32 points) allows conversion of measured values into any length, volume or flow units.
Two-wire or four-wire device for continuous non-contact level and flow measurement.
