ABSTRACT:
A vortex flowmeter for measuring the flow rate of a fluid flowing into a conduit, wherein a member 5a for disturbing the flow of the fluid is disposed upstream of a vortex generating column 3 for generating vortexes in the fluid to be measured, and upstream of a straightener 4 for uniforming the flow of the fluid into the conduit. The fluid flow is disturbed in both the flow direction and its orthogonal direction, and the generation of vortexes by the vortex generating column is facilitated, while the fluctuation of the generated vortexes is prevented.
