Abstract

L'invention est relative à un dispositif de mesure du débit d'une canalisation. Le dispositif est caractérisé en ce qu'il comporte un organe 6 sensible à la perte de charge engendrée par un orifice d'écoulement 40, 50 de section variable de manière continue asservi à un servo-mécanisme 60 qui fait varier la section dudit orifice à l'aide d'un élément mobile 5 pour y maintenir une perte de charge sensiblement constante, un calculateur 9 de débit en fonction de ladite perte de charge et de la section dudit orifice. L'invention s'applique notamment à l'exploitation des installations hydrauliques.The invention relates to a device for measuring the flow rate of a pipe. The device is characterized in that it comprises a member 6 sensitive to the pressure drop generated by a flow orifice 40, 50 of continuously variable section slaved to a servo-mechanism 60 which varies the section of said orifice to using a mobile element 5 to maintain a substantially constant pressure drop therein, a flow rate computer 9 as a function of said pressure drop and the section of said orifice. The invention applies in particular to the operation of hydraulic installations.
