Marmonix MEF-8700 Partial-Fill Mag Flow Meter

The Marmonix MEF-8700 is an electromagnetic flow meter built for partially filled pipes—irrigation canals, wastewater lines, and gravity drains where a full-pipe mag meter would read wrong. It combines velocity sensing with a mini ultrasonic level input so volume flow can be calculated from roughly 10% to 100% fill.

What the MEF-8700 partial-fill mag meter measures

Standard mag meters assume a full pipe. The MEF-8700 is sized for DN200–DN3000 flange installations with a remote LCD converter, Modbus/RS485 communications, and an optional solar power kit for remote sites without mains power.

Real use cases for the MEF-8700 electromagnetic flow meter

• Irrigation networks — open or partially filled conveyance where seasonal fill varies
• Wastewater & drainage — gravity lines that rarely run full
• Remote pumping / canals — solar-powered converter locations off the grid
• Municipal monitoring — large-diameter lines needing RS485/Modbus totals

MEF-8700 flow meter key specifications

• Pipe size DN200–DN3000, flange connection

• Liner: neoprene / polyurethane; electrodes SS316, Ti, Ta, HB, HC options
• Remote converter; Modbus RTU / TTL; RS232/RS485
• Protection: converter IP65; sensor IP65 standard, IP68 optional
• Ultrasonic level assist with small blind zone (about ±1 mm level accuracy per datasheet)
