Marmonix MFU-6200 Wall-Mounted Ultrasonic Flow Meter

The Marmonix MFU-6200 is a wall-mounted ultrasonic flow meter for continuous, non-invasive liquid flow and heat measurement. Transit-time clamp-on metering covers pipes about DN15–DN6000 with typical accuracy of 1% of reading above 0.2 m/s, bi-directional totals, 4–20 mA / OCT / relay outputs, and Modbus RTU RS-485 for water supply, HVAC, oils, and process lines.

MFU-6200 wall-mounted flowmeter key features

What the MFU-6200 delivers in plant rooms and process skids:

• Wall-mounted transit-time ultrasonic metering without cutting the pipe
• Pipe sizes DN15–DN6000 · velocity to about ±32 m/s
• Accuracy 1% of reading at rates >0.2 m/s · repeatability 0.2%
• Backlit LCD for instantaneous/total flow, heat, velocity, and time
• Outputs: 4–20 mA, OCT pulse, relay · Modbus RTU RS-485
• PT100 inputs for heat measurement · optional SD card logging
• Power: AC220V or DC24V · transducer IP65 (IP68 optional)

Where teams use the MFU-6200 ultrasonic flow meter

Typical applications for the MFU-6200 include:

• Water supply & HVAC — chilled/hot water loops and building energy metering
• Oils & non-conductive liquids — food oil, light oil, diesel fuel monitoring
• Process & marine — ballast, pharmaceutical, and onboard flow/heat checks
• Permanent plant installs — wall transmitter with remote transducers and Modbus

MFU-6200 ultrasonic flow meter questions

Is the MFU-6200 a portable or fixed meter?

The MFU-6200 is a wall-mounted fixed ultrasonic flow meter: the transmitter mounts on a wall or panel and transducers clamp on the pipe for continuous monitoring.

When should I choose MFU-6200 instead of MFU-6100?

Choose the MFU-6200 for plant-room wall installs with AC or DC power, Modbus RS-485, and optional SD logging; choose the MFU-6100 when you need a compact modular DC unit for OEM cabinets or multi-channel integrators.

What pipe sizes and liquids does the MFU-6200 support?

It supports about DN15–DN6000 on common pipe materials and works with ultrasonically conductive liquids such as water, seawater, oils, and many chemicals — confirm turbidity and aeration against the datasheet before install.
