Time-of-Flight measuring principle
The FDU93 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 25m (85ft), solids 15m (50ft).

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.
FMU 90 and FDU 93 ultrasonic system maintains level in vertical holding
silos precisly and elminated weekly cleaning and maintenance
requirements.
System using a ControlLogix 1756 HART Analog Input Module
