Abstract
L'invention est du domaine de la mesure des débits de fluide à l'aide de débitmètres du type à induction de vortex. Un débitmètre de l'invention comprend un tube d'écoulement 10 en travers duquel est monté un assemblage en forme d'obstacle 11 supportant en porte-à-faux une queue 12 au moyen d'un bras flexible 13; à l'intérieur du bras flexible une tige 14 reliée à un barreau 17 logée dans l'assemblage en forme d'obstacle reliée à une tête de couplage 21 à travers un diaphragme 19 formant pivot pour agir sur un capteur de force 22 et donner lieu à un signal électrique périodique dont la fréquence est celle des battements de la queue 12 et reflète la vitesse d'écoulement dans le tube; selon l'invention une répartition de la masse des parties vibrantes (queue 12 et barreau 17) est telle qu'elle rend le capteur insensible à des vibrations provenant des sources extérieures. Application à la mesure des débits dans des milieux soumis à des vibrations mécaniques.
