Endress+Hauser Ultrasonic measurement Time-of-Flight Prosonic FMU90-N42KB262BA2L transmitter

Endress+Hauser Ultrasonic measurement Time-of-Flight Prosonic FMU90-N42KB262BA2L

Field of application

Prosonic FMU90 separated version with field housing or top hat rail housing for control cabinet instrumentation are suited for continuous, non-contact level measurement of fluids, pastes, sludge and powdery to coarse bulk solids. Also the flow measurement in open channels and weirs is possible as the simultaneous measurement of level and flow in a storm water overflow basin with only 1 sensor. Up to 6 relays for tendency alarm, flow pulse output or backwater/sludge alarm, 1 or 2 channel version.

Level measurement of fluids and bulk materials with 1 or 2 sensors for measuring of up to 45m (148ft) and level limit detection. Pump control, rake control and as option: additional pump control function.

Calculations: Average, difference, sum

Application flow: Flow measurement in open channels and weirs with 1 or 2 sensors

Flow measurement with back water or sludge detection

Up to 3 totalizers and 3 counters

Counting or time pulse output for control of external units
