Ultrasonic measurement Time-of-Flight Prosonic FMU40

Field of Application :

The Prosonic FMU40 sensor is designed for continuous, non-contact level measurement in:

• Fluids, pastes, and coarse bulk materials
• Flow measurement in open channels and at weirs

Its two-wire or four-wire compact transmitter makes it ideal for applications involving:

• Storage tanks
• Agitators
• Stockpiles
• Conveyor belts

The envelope curve visualization on the on-site display enables real-time diagnostics for improved efficiency. Additionally, the linearization function (up to 32 points) allows conversion of measured values into length, volume, or flow rate.
