Import Dmf Mass Flowmeter — Buy in Bulk from Supplier in China

The DMF mass flowmeter is a Coriolis-type instrument designed for precise volumetric and mass flow measurement of liquids in food processing and chemical dosing systems. It operates using oscillating tubes to detect mass flow rate based on phase shift, with accuracy typically within ±0.2% of reading. The device is engineered for continuous operation in environments handling viscous fluids such as syrup, dairy, and cooking oil.

The sensor body is constructed from 316L stainless steel with a hygienic surface finish of Ra ≤ 0.8 μm, suitable for food-grade applications. Internal electronics are enclosed in an IP67-rated housing, and the display interface supports both analog and digital output signals (4-20mA, Modbus RTU). The flow range varies by model, with standard units covering 0.5 to 100 kg/min, calibrated for liquids with viscosities up to 1000 mPa·s.

This flowmeter is used by beverage manufacturers, dairy processors, and chemical blenders requiring repeatable dosing accuracy. Buyers commonly require NIST-traceable calibration certificates and FDA compliance documentation. Trade terms are typically FOB Shanghai, with lead times of 4 to 6 weeks. Payment is structured as 50% advance, 50% before shipment. Installation requires straight pipe runs upstream and downstream to meet accuracy specifications.
