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
Benefits
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
