A vortex flow meter is based on the principle of the Kármán vortex (Kármán vortex street). When a fluid (e.g. water or air) flows through an opening or an object, a vortex pattern called a Kármán vortex forms behind the object. The frequency of these vortices is proportional to the flow velocity of the fluid.
The vortex flow meter uses these vortices to measure the flow velocity of the fluid. A special sensor detects the vortices and converts them into electrical signals. These signals are then processed by a processor to calculate the flow rate of the fluid.
