ABSTRACT:
A vortex flowmeter utilizes a bluff body which has three sections: An upstream head member, an intermediate section co-extensive with the head member, having a width less than that of the head member, and a tail section having a width greater than the intermediate section but less than the head section. A differential pressure sensor is mounted in the intermediate section. For different pipe sizes the head member and tail section are varied but the intermediate section width is maintained constant. This allows interchangeability of the pressure sensor in the intermediate section.
