Endress + Hauser ultrasonic sensor for level and flow measurement Prosonic FDU91 application:

E+H Prosonic FDU91 sensor for continuous, non-contact level measurement of fluids and of bulk materials in silos, on belts, stockpiles and in crushers. Also for flow measurement in open channels and at weirs. Typically used in measurements in low structural heights.
• Process connection: Thread
• Temperature: -40 to +80°C (-40 to +176°F)
• Pressure: +0.7 to +4bar (+10 to +58psi)
• Maximum measuring range: Liquids 10m (33ft), solids 5m (16ft)
• Blocking distance: 0.3m (1ft)
• International explosion protection certificates

Endress + Hauser sensor Prosonic FDU91 advantages are:

• Integrated temperature sensor for Time-of-Flight correction. Accurate measurements are possible, even if temperature changes are present
• Hermetically welded PVDF sensor 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)
• Integrated heating against a build-up of ice at the sensor (optional) ensures reliable measurement
