ABSTRACT:
A flowmeter comprising a vortex generator generating and shedding vortices intermittently wherein the vortices are generated naturally by the fluid flowing around the vertex generator or generated artificially by the change of flow pattern resulting from the artificial manipulation of the vortex generator, and a pair of vortex sensing wings arranged in tandem, wherein the flow velocity is determined by measuring the frequency of the vortices naturally generated and shed by the vortex generator or by measuring the time of travel of the artificial vortices required to move from the vortex generator or the first wing to the second wing of the two tandem wings.
