Working principle of vortex flowmeter

Utilization of Vortex Flow MeterThe principle design of "Karman vortex street" can be widely used for flow measurement of gases, vapors, and liquids. The Karman vortex street theory refers to the unstable boundary layer separation that occurs when a resistive fluid is placed in a fluid under specific conditions. Two asymmetrically arranged vortices are generated on both sides downstream of the resistive fluid, and the release frequency of the vortices is related to the average velocity of the fluid flowing through the vortex generator and the characteristic width of the vortex generator.
