The Prosonic FMU90 can be installed in the field or on a DIN rail in an instrument cabinet. It is suitable for continuous, non-contact level measurement of liquids, pastes, sludge, powders and coarse bulk solids. It can also be used for flow measurement in open channels and weirs; with a single sensor it can simultaneously measure the level and flow of stormwater overflow basins. Up to 6 relays can trigger trend alarms, flow pulse output alarms or backwater/sludge alarms, with single-channel or dual-channel versions available.
Benefits
Simple menu-guided on-site operation with a six-line plain text display, available in 15 languages
On-site envelope curve display for simple instrument fault diagnosis
The FieldCare operating software allows convenient remote operation, fault diagnosis and measuring point documentation
Time-of-flight calibration via built-in or external temperature sensor
Linearization function (up to 32 points) converts the measured value into length, volume or flow in any unit
Online calculation of channel/weir flow based on built-in flow curves
Automatic FDU9x sensor recognition function
Application areas
Level measurement: with 1 to 2 sensors for level measurement of liquids and bulk solids; measuring range up to 45 m; limit detection; pump control systems; target control systems; optional: additional pump control function; calculation: average, difference, total; Flow measurement: with 1 to 2 sensors for flow measurement in open channels and measuring weirs; return flow measurement or sludge monitoring; up to 3 totalizers and 3 counters; counter or time pulse output for external control units
