A vortex flowmeter having a flow obstruction body or vortex forming bar (16, 17, 18) formed in a manner to provide enhanced generation of vortices across a wide range of Reynold numbers of the fluid being measured. The bar includes projections (16A, 17A, 18A) adjacent the lateral edges thereof which tend to cause formation of vortices at the leading lateral edges with respect to the direction of flow and enhance the formation of such vortices along the surfaces extending generally parallel to the flow. Additionally, the flowmeter disclosed provides a mounting (34, 36) for a sensor (37) which makes the device relatively insensitive to acceleration in the mounting structure or supporting pipe of the flowmeter. |
