Basic Working Principle of Vortex Flowmeter

A vortex flow meter works based on the principle of ‘Karman vortex street’ demonstrated in the below figure.

This principle essentially means that when an obstruction is placed in path of a flow, it can produce a series a vortices alternating from each side of the obstruction.The frequency of alternating of these vortices is proportional to the flow rate being obstructed.

The vortex type flow meter uses a small rod called ‘shredder bar’ or ‘bluff bar’ to shred vortices and these vortices produced is directly proportional to flow rate. These vortices can be measured using a pressure sensor and it calculates proportional flow rate. In some applications different type of sensor may use in place of pressure sensor.
