The vortex flowmeter is based on the Karman vortex street principle. It is mainly characterized by setting up a non-streamlined vortex generator (blocking the fluid) in the flowing fluid, and alternately generating two regular vortices on both sides of the vortex generator. It is widely applicable to industries such as petroleum, chemical engineering, metallurgy, thermal power, textile, and papermaking, for the measurement and control of superheated steam, saturated steam, compressed air, and general gases, water, and liquids.
