Vortex Flowmeter

Vortex Flowmeter


The vortex flowmeter is based on the Karman vortex theory and uses piezoelectric crystals to detect the vortex frequency generated when the fluid passes through the triangular column in the pipeline, thereby measuring the flow rate of the fluid. Vortex flowmeter is widely used in petroleum, chemical, power heating, and other industries.


The vortex flow meter is on the principle of Karman vortex street, to measure liquid, gas, vapor even turbid liquid including micro-grain and impurity.
