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).

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

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.
