MFM Series Coriolis Mass Flowmeter
The MFM Series Coriolis Mass Flowmeter operates on the Coriolis principle and measures mass flow directly, without the need for density, temperature, or pressure compensation. It achieves a liquid accuracy of up to ±0.15% and a turndown ratio of up to 30:1. With built-in density and temperature measurement, it covers nominal sizes from DN3 to DN200, making it suitable for demanding applications such as petrochemical, chemical, and food custody transfer, as well as oil and gas metering.

Features & Benefits
Direct Mass Flow Measurement, No Temperature/Pressure Compensation Needed
Coriolis principle delivers true mass flow directly, eliminating the temperature, pressure, and density compensation errors required by volumetric flowmeters. It simultaneously outputs volumetric flow, density, and temperature.
Dual U-Tube Design, High Sensitivity, Stable Zero
The dual U-shaped measuring tube with fully digital drive provides excellent small-signal resolution. On DN3, zero stability reaches 0.01 kg/h—ideal for micro-flow measurement.
Easy Installation, No Straight Pipe Required
No straight pipe or flow conditioner needed. Unaffected by installation orientation or on-site flow conditions; supports bi-directional flow, reducing piping design and installation costs.
Wide Temperature and Pressure Range for Harsh Service
Sensor versions: standard –70 °C to +200 °C; cryogenic –200 °C to +60 °C; high-temperature –40 °C to +350 °C. Standard pressure 4.0 MPa, high-pressure version up to 25 MPa, with secondary pressure-containing housing for safety.
Smart Transmitter with Multi-Protocol Communication
The transmitter supports 4–20 mA and frequency output, plus HART, RS485, Modbus, Profibus-PA, Foundation Fieldbus (FF), and APL—seamlessly integrating with DCS, PLC, and SCADA systems. Chinese/English interface, power-on self-test, self-diagnostics, and password protection.
