Ultrasonic measurement Time-of-Flight Prosonic FMU90: Transmitter in housing for field or top-hat rail mounting for up to 2 sensors FDU90/91/92/93/95/96.
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.
Simple, menu-guided operation with 6-line plain text display, 15 languages selectable
Envelope curves on the display for quick and simple diagnosis
Easy operation, diagnosis and measuring point documentation with the supplied "FieldCare" operating program
Time-of-Flight correction via integrated or external temperature sensors
Linearisation (up to 32 points, freely configurable) for the most common flumes and weirs pre-programmed and selectable
Online calculation of the flume-/weir-flows via integrated flow curves
Automatic detection of the sensors FDU9x
Field of application:
Level measurement of fluids and bulk materials with 1 or 2 sensors for measuring of up to 70m 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.
