A Vortex Flow Sensor functions as a flow meter, operating on the principle of the von Kármán effect. This effect causes vortices to form downstream of a bluff body placed in a flowing fluid. The vortices are proportional to the fluid’s velocity and can be detected by the sensor to measure the flow rate accurately.

How Does a Vortex Flow Sensor Work?

The Vortex Flow Sensor detects the frequency of vortices shed by the bluff body in the fluid flow. As fluid flows past the bluff body, vortices are formed alternately on either side. The sensor detects these vortices and converts the frequency into a flow rate measurement.
