Field of application
  • Continuous, non-contact level measurement of fluids and bulk material in silos, on belts, stockpiles and in crushers
  • Flow measurement in open channels and at weirs
  • Maximum measuring range
    • FDU90: 3 m (9.8 ft) in fluids. 1.2 m (3.9 ft) in bulk materials
    • FDU91/FDU91F: 10 m (33 ft) in fluids. 5 m (16 ft) in bulk materials
    • FDU92: 20 m (66 ft) in fluids. 10 m (33 ft) in bulk materials
    • FDU93: 25 m (82 ft) in fluids. 15 m (49 ft) in bulk materials
    • FDU95: 45 m (148 ft) in bulk materials
  • International explosion protection certificates
Benefits
  • Integrated temperature sensor for Time-of-Flight correction. Accurate measurements are possible, even if temperature changes are present
  • Hermetically welded PVDF sensors FDU91/92 for highest chemical resistance
  • Suited for rough ambient conditions thanks to separate installation from the transmitter (up to 300 m (984 ft))
  • Reduced build-up formation because of the self-cleaning effect
  • Weather resistant and flood-proof (IP68)
  • Dust-Ex and Gas-Ex certificates available
Measuring principle

The sensor transmits ultrasonic pulses in the direction of the product surface. There, they are reflected back and received by the sensor. The transmitter Prosonic S measures the time t between pulse transmission and reception. From t (and the velocity of sound c) it calculates the distance D from the reference point to the product surface.
