Ultrasonic level measurement: Prosonic S FMU90

Transmitter in housing for field or top-hat rail mounting for the ultrasonic sensors FDU91/91F/92/93/95/96 Your 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 "ToF-Tool - FieldTool Package" operating program. 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 The sensors of the former series FDU8x can be connected Field of application: Application for level measurements 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 (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 measurements: 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 units
