Abstract
A Karman vortex type flow measuring apparatus comprises a duct (1) for a fluid whose flow rate or flow velocity is to be measured, and a columnar vortex shedding member (2) extending within the duct transversely of the fluid flow direction. The fluid flow near the vortex shedding member has a width (X) of which the ratio (X/D) to the width (D) of the vortex shedding member lies within the range between 3 and 4. A highly accurate measurement can be achieved independently of the cross-sectional configuration of the duct and for a wide range of the fluid flow rate or flow velocity.
