ABSTRACT:
A flow meter in which a bluff body of elongated cross-section extends substantially normal to the axis of a conduit through which a fluid, which may be a liquid or a gas, passes so that vortices or whirls alternatingly breaking away from the body are formed in the fluid to opposite sides of the body, and in which the frequency of the alternatingly breaking vortices is proportionate to the speed, respectively the volume per time unit, of the fluid passing through the conduit. This frequency is measured by at least one feeler arranged in a measuring conduit located outside the first-mentioned conduit and in which the measuring conduit communicates through bores with the interior of the first-mentioned conduit to opposite sides of the bluff body.
