Abstract

L'invention concerne un dispositif et un procédé pour étalonner un capteur de débit massique. L'invention vise à réaliser des conditions d'écoulement facilement reproductibles pour l'étalonnage de capteurs de débits massiques. A cet effet, un dispositif d'étranglement est soumis à un fonctionnement critique pour développer la vitesse du son dans la section transversale la plus étroite, créant ainsi une indépendance vis à vis des fluctuations de pression côté aspiration.
