vortex flow meter is a specialized instrument designed for measuring the flow rate of liquids, gases, or steam in various industrial processes. It operates on the principle of the Von Kármán effect, where a bluff body (typically a shedder bar or a blunt object) is placed in the flow stream. As the fluid passes by the bluff body, vortices are formed alternately on either side, creating a pattern. The frequency of these vortices is directly proportional to the velocity of the flowing fluid, allowing the vortex flow meter to accurately determine the flow rate.
