Endress+Hauser FDU91-RG1AA ultrasonic measurement, Endress+Hauser Prosonic S FDU91. Ultrasonic sensor for level and flow measurement for connection to FMU9x (measuring range up to 10m).
The FDU91 ultrasonic sensor for continuous, non-contact and maintenance-free level measurement of fluids, pastes, sludges and powdery to coarse bulk materials. But also for flow measurement in open channels and measuring weirs. The measurement is unaffected by dielectric constant, density or humidity and also unaffected by build-up due to the self-cleaning effect of sensors. Suited for explosion hazardous areas. Maximum measuring range in liquids 10m (33ft), solids 5m (16ft).
