Flowma DMF-1 Series Coriolis Mass Flowmeter

Flowma DMF-1 is the integral and remote type Coriolis Mass Flowmeter. Both types have highly refined digital signal processing electronics, so that accurate and stable mass flow measurement is achieved. DMF-1 employs a flame-proof type converter case suitable for use in the hazardous area together with it’s intrinsically safety type detector.

DMF-1‘s signal processing, housing protection and its detector’s special decoupling system against external loads and vibrations, realize high perfeormance in real applications. Mass Flow Measurement according to the Coriolis principle. Almost all flowing materials including multi phase fluids, high viscosity liquids (pastes and slurries) and liquid with a certain content of gas. For difficult fluids (e.g. abrasive or highly corrosive fluids) and gases please contact your Beijing Sincerity representitave.
