The E+H Prosonic FDU91F Ultrasonic Level Sensor is designed 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).

Temperature range is -40 to 221°F (-40 to 105°C) with pressure 10 to 58psi (0.7 to 4bar). Time-of-Flight correction ensures accuracy, and the hermetically welded 316L construction provides excellent durability. Suited for rough ambient conditions, weather resistant and flood-proof (IP68). Hygienic process connections available for sanitary applications.
