Electromagnetic flowmeter for open channels and partially filled pipes, FLOW 55

Utilizing unique dual-sensing technology, the device combines electromagnetic induction with an integrated ultrasonic sensor to provide highly accurate detection of both liquid level and flow velocity. Specifically optimized for partially filled pipes, open channels, and gravity-fed systems, the unit achieves an outstanding accuracy of ±1–2% of the actual flow rate.

• Internal pipe diameter: DN80…DN600
• Flow velocity (min. / max.): 0,46…7,5 m/s
• Accuracy: ± 1…2 % of actual flow (depends on flow profile and level detection)
• Process Temperature: 0…+70 °C
• Coating materials: hard rubber
• Maximum working pressure: No pressure (gravity flow) or 10 bar if pipe is full
• Output signal: 2× pulse / flow switch (max. 400 Hz), 4 ... 20 mA, 1× RS485 interface (Modbus / M-Bus protocol), M-Bus, HART, Ethernet module (TCP/IP, integrated web server)
• An optional IoT module allows measured values to be transmitted wirelessly via NB-IoT to the cloud
• Data archiving on a micro-SD card
• Process connections: flange
• Maximum ambient temperature: 55 °C
• Power supply: 24 V AC / DC, 230 V AC
• Protection class: IP68 for sensor, IP65-IP68 for transmitter
