EUVORT Series Vortex Flowmeter


Vortex Flow Meter

Principle of Vortex meter is based on the Karman vortex street. When fluid flows through a bluff body, vortices are alternately formed on both sides with opposite directions of rotation. These vortices each generate small amount of pressure. The pressure fluctuations are recorded by the sensor and converted to electrical pulses. The vortices develop very regularly within the permitted limits of the meter. Therefore, the frequency of vortex shedding is proportional to the volume flow.
