The periodic shedding of eddies occurs first from one side and then from the other side of a bluff body (vortex-shedding body) installed perpendicular to the pipe axis. Vortex shedding generates a so-called “Karman Vortex Street” with alternating pressure conditions which the frequency is proportional to the flow velocity.
All the vortex flowmeters are factory tested and calibrated. A calibration certificate is included for each of the flowmeter.
