A Vortex Flowmeter operates based on the Von Kármán Vortex Street principle. When a fluid flows past a bluff body (a non-streamlined object) placed in the flow path, alternating vortices are shed downstream. The frequency of these vortices is directly proportional to the flow velocity of the fluid.
Bluff Body Formation: A specially designed bluff body is placed in the flow path inside the meter.
Vortex Shedding: As the fluid moves past the bluff body, vortices are created alternately on both sides.
Detection Mechanism: A sensor, typically a piezoelectric or capacitive element, detects the pressure fluctuations caused by the vortex shedding.
Frequency Measurement: The frequency of vortex shedding is measured and is directly proportional to the flow rate.
Flow Rate Calculation: The meter converts the vortex frequency into volumetric or mass flow rate using calibration factors.
