Abstract

L’invention concerne un dispositif de détermination de la quantité de fluide, notamment de gaz, circulant dans un conduit de fluide, comprenant un débitmètre à oscillation fluidique (1) agencé sur un conduit de fluide (30) configuré pour réaliser des mesures de pression correspondant à des oscillations fluidiques se produisant au sein dudit débitmètre à oscillation fluidique (1), et un module de pilotage et de traitement de signal (4) configuré pour traiter les signaux de mesure de pression délivrés par le débitmètre à oscillation fluidique (1). Le module de pilotage et de traitement de signal (4) est configuré pour transformer les signaux de mesure de pression en un signal analogique comprenant une succession de fronts montants et de fronts descendants entre des niveaux logiques hauts (LH) et des niveaux logiques bas (LB) ; opérer un comptage des fronts montants ou des fronts descendants pendant une période de temps (T) et en déduire un nombre d’oscillations (No) pendant ladite période de temps (T) ; et déterminer un quantité de fluide (V) s’étant écoulée dans le conduit de fluide à partir du nombre d’oscillations (No) sur une période de temps (T).
