The vortex shedding flowmeter is a speed type flow meter and has wide application. It is suitable for metering and controlling the flow of liquid, steam and most of gas. The basic principle of the vortex street flowmeter is the karman vortex street principle, namely 'vortex street vortex separation frequency is in direct proportion to flow velocity'. A column body similar to an isosceles triangle is inserted in the circulation body, the axis of the column body is perpendicular to the flowing direction of the medium to be measured, and the bottom surface faces the fluid. When the medium to be measured flows through the column, vortexes are alternately generated at two sides of the column, the vortexes are continuously generated and separated, and two rows of vortexes which are staggered are formed at the downstream of the column, namely 'vortex street'.
The installation of the existing vortex shedding flowmeter is required to be installed and replaced under the condition that no medium exists in a pipeline, the on-line installation requirement cannot be met, a large amount of loss can be caused when production is stopped at each time, and the vortex shedding flowmeter cannot be used on pipelines which cannot be stopped.
