FMD-XX Wedge Flowmeter

FMD-XX wedge flowmeter is a flow meter that uses a V-shaped throttling element for flow measurement. Its sleek top angle faces downwards, which facilitates the smooth passage of liquids containing suspended particles or viscous liquids without stagnant flow upstream of the throttle.

FMD-XX wedge flowmeter is a flow meter that uses a V-shaped throttling element for flow measurement. Its sleek top angle faces downwards, which facilitates the smooth passage of liquids containing suspended particles or viscous liquids without stagnant flow upstream of the throttle. The wedge flowmeter can be used for flow measurement of viscous liquids, and the viscosity can be as high as 500mPaS, used for flow measurement of slurry, ore slurry, sandy crude oil, sewage, heavy oil, residual oil and other solid suspensions and low Reynolds number and other liquid media. It can also be used for the flow of gas and steam media. This product is used for various gases, especially suitable for the flow measurement of dirty gas and natural gas.
