Vortex flow meters are flow sensors that detect the frequency of vortices shed by a bluff body placed in a flow stream. The frequency of the vortices is proportional to the flow velocity.
Flow rate information can be output as an analog current signal.
k factor is introduced to compensate for the non-uniform profile of pipe flow.

State four different types of flow measurement, for gas flow measurement MMSCFD is the common unit expand the unit and specify significance of word S in the unit.
