Abstract
(EN) An ultrasonic transducer for a pipe includes an ultrasonic source which produces plane waves. The transducer includes a housing having a face at least a portion of which is curved through which the plane waves produced from the source disposed in the housing are emitted and directed outward towards the pipes interior wall so a full cross-section of the pipes interior can be measured. A flow meter for detecting fluid flow rates in a pipe. A method for detecting fluid flow rates in a pipe.
(FR) La présente invention concerne un transducteur ultrasonore destiné à une conduite, qui comprend une source ultrasonore qui produit des ondes planes. Le transducteur comprend un boîtier ayant une face, dont au moins une partie est incurvée et à travers laquelle les ondes planes produites depuis la source disposée dans le logement sont émises et dirigées vers l'extérieur, vers la paroi intérieure des conduites afin qu'une section transversale complète de l'intérieur des conduites puisse être mesurée. L'invention concerne également un débitmètre permettant de détecter des débits fluidiques dans une conduite. L'invention concerne enfin un procédé permettant de détecter les débits fluidiques dans une conduite.
