Abstract
This invention discloses a vortex shedding flowmeter comprising a vortex generating member disposed across one cross section of the flow passage and a vortex sensing member including a wing disposed across another cross section of the flow passage parallel to the vortex generating member, wherein one extremity of the wing is secured to a stocky container member housing a piezoelectric element by a flange of a thin diaphragm construction, which stocky container member is rigidly secured to the wall of the flow passage, while the other extremity of the wing is secured to the opposite side wall of the flow passage in a resilient manner.
