摘要：A flow meter in which a bluff body of elongated cross-section extendssubstantially normal to the axis of a conduit through which a fluid, which may be a liquidor a gas, passes so that vortices or whirls alternatingly breaking away from the body areformed in the fluid to opposite sides of the body, and in which the frequency of thealternatingly breaking vortices is proportionate to the speed, respectively the volumeper time unit, of the fluid passing through the conduit. This frequency is measured by atleast one feeler arranged in a measuring conduit located outside the first-mentionedconduit and in which the measuring conduit communicates through bores with the interiorof the first-mentioned conduit to opposite sides of the bluff body.
