Məlumat

Transmitter in housing for field or top hat rail mounting for up to 2 sensors FDU90/91/92/93/95

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

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

Time-of-Flight measuring principle
