Abstract
A Karman vortex flow meter including an upstream columnar body having a substantially isosceles triangular cross section and a downstream columnar body having a substantially isosceles trapezoidal cross section. The downstream columnar body has a base surface which is substantially equal in width to the base surface of the upstream columnar body. The two bodies are positioned in a stream of a fluid with their base surfaces disposed at a distance from each other in mutually parallel relation and at right angles to the stream for generating Karman vortices to measure the flowing speed or rate of the fluid based on the frequency of the vortices. The upstream columnar body has a pair of rounded edges along its base surface.
