Process Pressure:
0.7 bar to 3 bar abs (10 psi to 44 psi)
Max. Measurement Distance:
Liquids: 5 m (16 ft)
Solids: 2 m (6.6 ft)
Main Wetted Parts:
PVDF (Polyvinylidene fluoride)
Field of Application:
The Prosonic FMU40 sensor is designed for non-contact level measurement in fluids, pastes, bulk materials, and flow measurement in open channels or weirs. It is suitable for use in storage tanks, agitators, stockpiles, and conveyor belts. The sensor features envelope curve display on-site for easy diagnostics and includes a linearization function for converting the measured values into length, volume, or flow rate units.
Reliable Non-Contact Measurement:
Accurate level measurement without physical contact with the medium.
Easy Commissioning:
On-site, menu-guided setup with a four-line plain text display in 7 selectable languages.
Envelope Curve Display:
A visual tool for simple diagnostics and troubleshooting.
Chemically Resistant Sensor:
Made from durable PVDF, ideal for chemically harsh environments.
Temperature Compensation:
An integrated temperature sensor adjusts the measurement based on the temperature-dependent sound velocity.
Calibration:
Calibration without the need for filling or discharging the tank.
Process Conditions:
Operating Temperature: -40 to +80°C (-40 to +176°F)
Pressure Range: 0.7 to 3 bar (10 to 44 psi)
Probes & Installation:
Process Connection: G or NPT 1½” thread
Blocking Distance:
Liquids & solids: 0.25 m (0.8 ft)
Communication & Integration:
Communication: 2-wire HART (4…20 mA)
