Ultrasonic sensors for level and flow measurement for connection to FMU9x
• Continuous, non-contact level measurement of fluids and bulk material in silos, on belts, stockpiles and in crushers
• Flow measurement in open channels and at weirs
• Maximum measuring range
– FDU90: 3 m (9.8 ft) in fluids 1.2 m (3.9 ft) in bulk materials
– FDU91/FDU91F: 10 m (33 ft) in fluids 5 m (16 ft) in bulk materials
– FDU92: 20 m (66 ft) in fluids 10 m (33 ft) in bulk materials
– FDU93: 25 m (82 ft) in fluids 15 m (49 ft) in bulk materials
– FDU95: 45 m (148 ft) in bulk materials
• International explosion protection certificates
• Integrated temperature sensor for Time-of-Flight correction.
Accurate measurements are possible, even if temperature changes are present
• Hermetically welded PVDF sensors FDU91/92 for highest chemical resistance
• Suited for rough ambient conditions thanks to separate installation from the transmitter (up to 300 m (984 ft))
• Reduced build-up formation because of the self-cleaning effect
• Weather resistant and flood-proof (IP68)
• Dust-Ex and Gas-Ex certificates available
