Abstract

a. Mesureur de débit de type à oscillateur fluidistor. b. Mesureur de débit caractérisé en ce qu'il est de forme très compacte et en ce que les oscillations de débit provoquées entre ses deux conduits de sortie sont détectées à l'aide d'un émetteur et d'un récepteur d'ultrasons formant une liaison par ondes de compression traversant le débit de fluide à mesurer. c. L'invention s'applique notamment aux mesures de débits respiratoires chez l'homme et chez les animaux.at. Fluidistor oscillator type flow meter. b. Flow meter characterized in that it has a very compact shape and in that the flow oscillations caused between its two outlet ducts are detected using an ultrasound transmitter and receiver forming a link by compression waves passing through the flow of fluid to be measured. vs. The invention applies in particular to measurements of respiratory flow rates in humans and in animals.
