Field of application
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.
Two-wire or four wire instrument for continuous non-contact level and flow measurement.
Process connection: Thread
Temperature: -40 to +80°C (-40 to +176°F)
Pressure: +0.7 to +3bar (+10 to +44psi)
Maximum measuring distance: Liquids 8m (26ft), Solids 3.5m (11ft)
Blocking distance: Liquids and Solids 0.35m (1.15ft)
International explosion protection certificates
