Description

Vortex flow meter is one kind of velocity type flow meter, it’s based on Karman vortex theory and adopts piezoelectric 

crystal to detect the burble frequency of the fluid caused by flowing through the triangular prism in the pipeline and then 

measure the flow of fluid. It is widely used in petrol, chemical industry, light industry and power heat supply and so on.
