Transmitter for 1 or 2 Ultrasonic Sensors Prosonic FMU90

Application

The Prosonic FMU90, available in a separate field housing or DIN rail housing for control cabinet installations, is ideal for continuous, non-contact level measurement of liquids, pastes, slurries, and from fine powders to coarse bulk solids. It also supports flow measurement in open channels and weirs, and can simultaneously measure level and flow in stormwater overflow basins using a single sensor. The system features up to 6 relays for applications such as trend alarms, flow pulse output, and backwater/sludge alarms, and is available in one or two-channel configurations.

It can measure levels up to 45 meters (148 feet) and detect level limits for both liquids and bulk materials using one or two sensors. The device supports various functions including pump control, rake control, and an optional additional pump control feature.

Calculations include average, difference, and sum values.

Application Scenarios:

• Flow measurement in open channels and weirs with one or two sensors
• Flow measurement with backwater or sludge detection
• Up to three totalizers and three counters
• Counting or time pulse output for controlling external devices

Benefits

• User-Friendly Operation: Simple, menu-guided interface with a 6-line plain text display and 15 selectable languages.
• Efficient Diagnostics: Envelope curve display for quick and straightforward diagnostics.
• Easy Setup and Management: Convenient operation, diagnosis, and measurement documentation through the included "FieldCare" software.
• Accurate Measurement: Time-of-Flight correction using integrated or external temperature sensors.
• Customizable Linearization: Up to 32 freely configurable linearization points, pre-programmed and selectable for common flumes and weirs.
