ABSTRACT:
A vortex flowmeter is provided with a vortex-inducing bluff body in the form of a first, upstream, cylinder having a semi-circular or semi-ellipsoidal front surface and a planar rear surface, and a second, downstream, cylinder having a planar front surface and a planar or concave rear surface. The rear surface of the upstream cylinder is parallel to the front surface of the downstream cylinder, and separated from it by a gap whose width is preferably about 25% of the diameter of the upstream cylinder.
