Title
(EN) VORTEX SENSING PRESSURE TRANSDUCER
(FR) TRANSDUCTEUR DE PRESSION DETECTANT UN TOURBILLON
Abstract
(EN)
A vortex flowmeter employs a differential pressure transducer converting oscillation in a differential pressure to an alternating electrical signal, wherein the differential pressure transducer comprises a pair of pressure compartments (10 and 11) respectively receiving two fluctuating fluid pressures respectively existing at two fluid regions located on the two opposite sides (8 and 9) of a vortex generator (3) respectively through a pair of tubings (13 and 14, 43 and 44, or 61 and 62) or through a pair of holes (69 and 70, or 72 and 73) embedded within the wall of the flow passage.
(FR)
Un débitmètre à tourbillons met en oeuvre un transducteur de pression différentielle transformant une oscillation d'une pression différentielle en un signal électrique alternatif. Le transducteur de pression différentielle comporte une paire de compartiments de pression (10 et 11) recevant respectivement deux pressions fluidiques oscillatoires présentés respectivement au niveau de deux régions de fluide situées sur les deux côtés opposés (8 et 9) d'un générateur de tourbillons (3), à travers une paire de tubes (13 et 14, 43 et 44 ou 61 et 62), ou une paire d'orifices (69 et 70 ou 72 et 73) encastrés dans la paroi du passage d'écoulement.
