  • 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.

    • 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

    Two-wire or four wire instrument for continuous non-contact level and flow measurement.
