Ultrasonic measurement Time-of-Flight Prosonic FMU41

Field of Application :

The Prosonic FMU42 sensor is suited for non-contact level measurement in:

• Fluids, pastes, and coarse bulk materials
• 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
• Stockpiles
• Conveyor belts

The envelope curve can be shown on the on-site display for simple diagnosis. The sensor also features a linearization function (up to 32 points) for conversion of the measured value into any unit of length, volume, or flow rate.
