Field of application
The Prosonic FMU42 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.
Two-wire or four wire instrument for continuous non-contact level and flow measurement.
Process connection: Flange
Temperature: -40 to +80°C (-40 to +176°F)
Pressure: +0.7 to +2.5bar (+10 to +36psi)
Maximum measuring distance: Liquids 10m (33ft), Solids 5m (16ft)
Blocking distance: Liquids and Solids 0.4m (1.3ft)
International explosion protection certificates
