Intelligent Mass Flowmeter(flow meter) Intelligent mass flowmeter is basing on principle of Coriolis force effect and can be available in the fluid measurement in oil refining, petrochemical industry, metallurgy, food and drinking, pharmacy, papermaking, dye and so on field. There are no chocking flow element and movable element with structure, so it has more advantage in measuring the mass flow-rate of these sticky even hard to flow medium (as coal tar, residual oil, food syrup, pulp, latex, mixed gum) and these fluctuating flow medium. Practice approves that it can measure the gas flow at high pressure, but it fail to measure the flow of gas-liquid mixed fluids.
