Endress+Hauser Time-of-Flight Prosonic Fmu40 Ultrasonic Level Liquid Transmitter

Endress+Hauser Time-of-Flight Prosonic Fmu40 Ultrasonic Level Liquid Transmitter
Product Description
Endress+Hauser E+H Time-of-Flight Prosonic Fmu40 Ultrasonic Level Liquid Transmitter
Field of application
The Prosonic FMU40 sensor is suited for non-contact level measurement in fluids, pastes, coarse bulk material and flow measurement in open channels or at weirs. The two-wire or four-wire compact transmitter can be used in applications with storage tanks, agitators, on stockpiles and conveyor belts. The envelope curve can be shown on the on-site display for simple diagnosis. Linearization function (up to 32 points) for conversion of the measured value into any unit of length, volume or flow rate
