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