High Accuracy Viscosity Resistant Duplex Rotor Flowmeter

The MG9860 Duplex Rotor Flowmeter is a next-generation positive displacement meter featuring a dual-cavity, screw-rotor design that delivers pulsation-free, low-noise operation with accuracy up to ±0.2%. It excels in measuring high-viscosity liquids such as crude oil, refined products, and chemical raw materials with minimal pressure loss. The instrument provides on-site mechanical readout and can be equipped with transmitters for 4–20 mA, HART, or Modbus outputs, enabling seamless integration into automated control systems. Widely used in petroleum, chemical, metallurgy, power, transportation, and marine industries.
