E+H Prosonic FDU91F Ultrasonic Level Transmitter

The Endress Hauser FDU91F ultrasonic sensor for continuous, non-contact and maintenance-free level measurement of fluids, pastes, sludges and powdery to coarse bulk materials. Also for flow measurement in open channels and at weirs. Measurement is unaffected by dielectric constant, density or humidity and also unaffected by build-up due to the self-cleaning effect of sensors. Fully welded 316L with hygienic process connection available. Maximum measuring range in liquids 10m (33ft), solids 5m (16ft).

  • Integrated temperature sensor for Time-of-Flight correction. Accurate measurements are possible, even if temperature changes are present
  • Hermetically welded sensors (316L, 1.4404, 1.4435) for highest chemical resistance
  • Suited for rough ambient conditions thanks to separate installation from the transmitter 
    (up to 300m)
  • Reduced build-up formation because of the self-cleaning effect
  • Integrated automatic sensor detection for transmitters FMU90/FMU95 for simple commissioning
  • Weather resistant and flood-proof (IP 68)
  • Hygienic process connections available
