Time-of-Flight measuring principle

Hygienic sensor for level and flow measurement for connection to FMU9x (measuring range up to 10m)

The 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).

  • Voordelen

    • 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...

  • Toepassingsgebied

    Continuous, non-contact level measurement of fluids and bulk materials in silos, on belts, stockpiles or in crushers. Also for flow measurement in open channels and at weirs. Used in measurements in low structural heights.

    • Process connections: Thread,...
