Principle
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 whose frequency "f" is proportional to the flow velocity "V". The non-dimensional Strouhal number "S" (primary head constant) describes the relationship between Vortex shedding frequency F (in Hz) width b of the body, and mean flow velocity v (in m/s) F=S+v/b.

The flexural vibration of the Vortex-shedding body is picked up in the primary head via sensors and analyzed in the signal converter. In the case of the gaseous, flowing media, the vibration frequency ranges between 10 and 7000 Hz.
