ABSTRACT:
A vortex flow meter capable of operating with minimum piping effect is disclosed. A stream-lined protrusion , extending toward the upstream side is disposed at the upstream surface 2 of a vortex generator joined to the inner wall 1 of a flow pipe in order to remove thereat horseshoe vortexes produced in front of the vortex generator. Therefore, the possible affection of horseshoe vortexes, that may considerably depend upon the piping conditions, can be eliminated.
