Application Area
The Prosonic FMU41 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. Diagnostics are simplified thanks to the echo curve display on the built-in 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.
