Abstract
L'INVENTION CONCERNE UN DEBITMETRE UTILISANT LA RUE DES VORTICES DE KARMAN. SELON L'INVENTION, UN FLUIDE S'ECOULE A TRAVERS UN CONDUIT 10 ENDUIT D'UN MATERIAU 12 ABSORBANT LE SON. UNE TIGE 14 GENERATRICE DE TOURBILLONS EST DISPOSEE PERPENDICULAIREMENT A LA DIRECTION D'ECOULEMENT DU FLUIDE DANS LE CONDUIT POUR PRODUIRE UNE RUE DES VORTICES DE KARMAN 16 EN AVAL D'ELLE-MEME. UNE ONDE ULTRASONIQUE EST EMISE PAR UN TRANSMETTEUR 18 QUI EST DISPOSE SUR LE CONDUIT IMMEDIATEMENT EN AVAL DE LA TIGE ET ELLE EST MODULEE PAR LES TOURBILLONS DE KARMAN. L'ONDE MODULEE EST RECUE PAR UN RECEPTEUR D'ULTRA-SONS 22 DISPOSE SUR LE CONDUIT EXACTEMENT EN FACE DU TRANSMETTEUR. L'ONDE RECUE DONNE UNE MESURE DU NOMBRE DE TOURBILLONS EN UN TEMPS UNITAIRE ET PAR CONSEQUENT D'UN DEBIT DU FLUIDE. L'INVENTION S'APPLIQUE NOTAMMENT A LA MESURE DES DEBITS.
