Prosonic FMU41

Prosonic FMU41 ©Endress+Hauser

Time-of-Flight measuring principle

  • Prosonic FMU41

Cost effective device for sophisticated level measurement in liquids and bulk solids for up to 8m

The Prosonic FMU41 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.
