Fluid flow measuring apparatus |
摘要 |
A Karman vortex type flow rate measuring apparatus is provided with a plurality of vortex shedding members each having a different effective width, and a plurality of vortex detecting elements. The distance between the vortex detecting elements is so selected that it coincides with the distance between the vortices of some one of the vortex trains induced by respective vortex shedding members. The apparatus enables a positive and accurate detection of the vortices, and a compensation for drop out of the vortex shedding.
