E+H Prosonic FMU43 Ultrasonic Sensor Introduction

E+H Prosonic FMU43 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.

E+H Prosonic FMU43 Ultrasonic Sensor Feature


  • 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
