The Prosonic FMU44 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.
