Abstract
Appareil de mesure du débit-masse d'un fluide. Il comprend deux tubes vibrants en forme de U qu'un vibrateur fait osciller et des capteurs du couple des forces de Coriolis résultant des oscillations et de l'écoulement de la matière dont le débit doit être mesuré par l'appareil. Les tubes comprennent des éléments d'entrée et de sortie espacés qui sont reliés à un élément fixe par une extrémité. Des détecteurs sont montés à leur autre extrémité. Les extrémités fixes sont plus rapprochées que les autres extrémités sur lesquelles sont montés les détecteurs afin d'augmenter le bras de levier par lequel le couple des forces de Coriolis agit et de détecter plus facilement une torsion des tubes en U. Application à la mesure du débit-masse d'un fluide
