Prosonic S FMU90
Transmitter in housing for field or top-hat rail mounting

for the ultrasonic sensors FDU90/91/91F/92/93/95/96

Application for level measurement
• Continuous, non-contact level measurement of fluids,
pastes, sludge and powdery to coarse bulk materials
with 1 or 2 ultrasonic sensors
• Measuring range up to 70 m (230 ft)
(depending on sensor and material measured)
• Level limit detection (up to 6 relays)
• Pump control (alternating); rake control
• Option: additional pump control functions (pump
function test, …)
• Calculations: average, difference, sum
Application for flow measurement
• Flow measurement in open channels and measuring
weirs with 1 or 2 ultrasonic sensors
• Simultaneous measurement of level and flow in a
stormwater overflow basin with only 1 sensor
• Flow measurement with back water detection (2
sensors) or sludge detection
• Up to 3 totalizers and 3 (resettable) counters;
optionally resettable via digital inputs
• Counting or time pulse output for control of external

Your benefits
• Simple, menu-guided operation with 6-line plain text
display; 15 languages selectable
• Envelope curves on the display for quick and simple
• Easy operation, diagnosis and measuring point
documentation with the supplied Endress+Hauser
operating program “FieldCare”.
• Option: four digital inputs (e.g. for pump feedback)
and one external temperature input
• Time-of-flight correction via integrated or external
temperature sensors
• Linearisation (up to 32 points, freely configurable)
• Linearisation tables for the most common flumes and
weirs pre-programmed and selectable
• Online calculation of the flume-/weir-flows via
integrated flow curves
• Pre-programmed pump control routines
• System integration via HART or PROFIBUS DP
• Automatic detection of the sensors FDU9x
