±2 mm + 0.17% of measured distance
Applications
The Prosonic FMU90 model features a separate housing for field mounting or DIN-rail installation, designed for continuous non-contact level measurement of liquids, pastes, slurries, and bulk materials of varying particle sizes. It can measure flow in open channels and weirs, as well as simultaneously monitor level and flow in stormwater overflows using just one sensor. Offers up to 6 relays for trend alarms, flow pulse output, or backflow/sludge detection, available in 1 or 2-channel versions.
Level measurement of liquids and bulk materials with 1 or 2 sensors up to 45 m (148 ft), including limit level monitoring. Pump and rake control, with an optional pump control function.
