ABSTRACT:
A Karman's vortex street flow meter has two conduits through which a fluid to be measured flows, a vortex generating portion disposed at a junction where those portions of the fluid flowing through the respective conduits join each other, a plurality of vortex stabilizers disposed at predetermined equal intervals downstream of the vortex generating portion, and a detector for detecting the frequency at which vortices of a Karman's vortex street are generated downstream of the vortex generating portion to sense the flow speed or the flow rate of the fluid.
