Abstract
A vortex flow meter is comprised of a vortex generator provided in a fluid to be measured and a tube member installed in a direction intersecting with it at the downstream side. The tube member includes at least a couple of holes arranged at intervals of predetermined distances in the direction of the shaft. A pressure variation due to the Karman vortex created by the vortex generator is applied to the fluid in the tube member through the above-mentioned holes. A detector for sensing the pressure variation is installed in the tube member. The number of Karman vortexes is counted by the pressure variation detector.
