Abstract
Procédé et appareil de mesure du débit massique d'un fluide. On fait passer le fluide dans un corps creux, on mesure ses températures à l'entrée et à la sortie ainsi que la déperdition de chaleur par la paroi du corps et on en déduit le débit massique à partir de l'équation du bilan thermique. L'appareil comprend un tube 2 équipé de sondes thermométriques et entouré de deux enroulements concentriques 3, 5 qui sont composés de fils dont la résistance varie avec la température et qui sont séparés par un matelas 4 à faible conductibilité thermique. Ces sondes et ces enroulements sont reliés à un calculateur électronique. Application notamment à la mesure de débits massiques très faibles.
