A vortex flow meter is a type of flow meter used to measure the flow of liquids, gases, and steam in pipelines. It is based on the principle of measuring the frequency of vortices generated when a fluid flows around a bluff body. As the fluid passes the bluff body, it creates vortices that are shed alternately from either side of the body. These vortices are detected by a sensor and the frequency of the vortices is proportional to the flow velocity. Vortex flow meters are known for their high accuracy, low maintenance, and reliable performance. They are commonly used in industries such as chemical, petrochemical, food and beverage, and water treatment.
