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