Abstract

L'invention est du domaine des appareils de mesure des débits. Elle a pour objet un adaptateur pour débitmètre à induction de vortex incorporant un tube d'écoulement formant un passage cylindrique à travers lequel peut passer le fluide dont on veut mesurer le débit, et un obstacle composite monté dans le tube pour créer des vortex dont la fréquence est fonction de la vitesse d'écoulement, ledit obstacle composite incorporant un bloc disposé en travers du tube perpendiculairement à la direction d'écoulement, caractérisé en ce qu'il comprend des moyens tels que deux baguettes 21A et 21B pour réduire la section effective de passage ce par quoi ledit débitmètre rend compte de vitesses d'écoulement qui se trouveraient situées au-dessous de la plage normale de travail du débitmètre. Application à la mesure des débits de liquides et de gaz.
