Vortex flowmeter is one of the main flowmeter products, widely used in petroleum, chemical industry, metallurgy, heating and other departments. it can measure the flow of many kinds of liquid, gas and steam.
The vortex flow sensor is based on the theory of Karman and Strohal about the generation of vortices and the relationship between vortices and flow to measure the steam, gas and low viscosity liquid. A triangular column is inserted vertically into the meter body, that is, the generator of the vortex. When there is a medium flowing through the meter body, a regular Karman vortex in the opposite direction is alternately generated behind the triangular column, and the separation frequency F of the vortex is proportional to the flow velocity V of the medium. By detecting the number of vortices through the sensing head, the fluid velocity can be calculated, and then the volume flow of the measured medium can be calculated according to the surface diameter.
