Endress+Hauser Prosonic FDU92 Ultrasonic measurement Time-of-Flight

• 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)
• International Dust-Ex and Gas-Ex certificates available

Sensor for continuous, non-contact level measurement of fluids and 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.
