E+H Prosonic FMU40 Ultrasonic Level Transmitter

The Endress+Hauser 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, 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 converting the measured value into any unit of length, volume, or flow rate.

  • Reliable non-contact measurement
  • Quick and simple commissioning via menu-guided on-site operation with four-line plain text display, 7 languages selectable
  • Envelope curves on the on-site display for simple diagnosis
  • Hermetically sealed and potted sensor
  • Chemically resistant sensor out of PVDF
  • Calibration without filling or discharging
  • Integrated temperature sensor for automatic correction of the temperature dependent sound velocity
