Vortex flowmeter principle: Karman vortex principle. Insert a vortex generator (trapezoidal, cylindrical, triangular) into a uniform fluid, and the fluid will alternately generate uniform vortices on both sides behind the generator. The number of vortices is proportional to the fluid flow rate. The measured number of vortices can be used to obtain the fluid flow rate.
