Ultrasonic measurement
Time-of-Flight
Prosonic FDU90
Time-of-Flight measuring principle
Ultrasonic sensor for level and flow measurement for connection to FMU9x (measuring range up to 3m)
The FDU90 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 3m (9.8ft), solids 1.2m (3.9ft).

Benefits
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...
-
Field of application
Sensor for continuous, non-contact level measurement of fluids and bulk materials in silos, on belts, stockpiles and in crushers. Also flow measurement in open channels and at weirs. Typically used in measurements in low structural heights.

Level measurement in polymer station with ultrasonic level sensor
For the different treatment processes, wastewater plants produce huge
amounts of sewage sludge annually. Since this must be disposed of
through landfill or incineration, it is essential to try to render
residual
sludge as dry as possible.Case Studies (CS)06/11English -
