Title (EN) VORTEX SHEDDING FLOWMETER CONSTRUCTION
(FR) CONSTRUCTION D"UN INDICATEUR DE DEBIT A FORMATION DE VORTEX
Abstract: front page image
(EN)A vortex flowmeter having a flow obstruction body or vortex forming bar (16, 17, 18) formed in a manner to provide enhanced generation of vortices across a wide range of Reynold numbers of the fluid being measured. The bar includes projections (16A, 17A, 18A) adjacent the lateral edges thereof which tend to cause formation of vortices at the leading lateral edges with respect to the direction of flow and enhance the formation of such vortices along the surfaces extending generally parallel to the flow. Additionally, the flowmeter disclosed provides a mounting (34, 36) for a sensor (37) which makes the device relatively insensitive to acceleration in the mounting structure or supporting pipe of the flowmeter.
(FR)Un indicateur de debit a vortex possede un corps d"obstruction du debit ou barre de formation de vortex (16, 17, 18) dont la forme augmente la production de vortex a travers une large gamme de nombres de Reynolds de l"ecoulement mesure. La barre ou corps comprend des saillies (16A, 17A, 18A) adjacentes a ses bords lateraux qui ont tendance a provoquer la formation de tourbillons au niveau des bords lateraux d"attaque par rapport au sens de debit et augmentent la formation de tels tourbillons le long des surfaces se prolongeant parallelement au sens du debit. De plus, l"indicateur de debit de l"invention presente un montage (34, 36) pour un capteur (37), ce qui rend le dispositif relativement insensible aux accelerations dams la structure de montage ou le tuyau de support de l"indicateur de debit.
