The E+H Prosonic S FMU90 transmitter features continuous, non-contact level measurement of fluids, pastes, sludge, and powdery to coarse bulk solids. The transmitter also measures flow in open channels and weirs with one or two sensors, including pre-programmed and selectable linearization for the most common flumes and weirs. It features up to six relays for tendency alarm, flow measurement with backwater or sludge detection, up to three totalizers and three counters, and counting or time pulse output for control of external units. Integrated or external temperature sensors enable time-of-flight correction.

The FMU90 transmitter offers a one- or two-channel version and the choice of field housing or top hat rail housing for control cabinet instrumentation. The display features envelope curves for quick and simple diagnosis, and the supplied "FieldCare" operating program enables easy operation, diagnosis, and measuring point documentation.
