| Abstract | A method for determining the instantaneous flow rate of a fluid in a pipeline (8) comprising the phases of : - measuring the difference in pressure of the fluid in at least two points of said pipeline (8) longitudinally set apart at a certain distance (1) to calculate the related pressure gradient, and - determining the instantaneous flow rate by using the value of the pressure gradient in a model based on a system of differential equations including the mass conservation equation and the momentum balance equation.
L'invention porte sur un procédé pour déterminer le débit instantané d'un fluide dans une canalisation (8) comprenant les phases consistant à : mesurer la différence de pression du fluide dans au moins deux points de ladite canalisation (8) espacés longitudinalement à une certaine distance (1) pour calculer le gradient de pression apparenté, et déterminer le débit instantané à l'aide de la valeur du gradient de pression dans un modèle basé sur un système d'équations différentielles comprenant l'équation de conservation de masse et l'équation d'équilibre des quantités de mouvement. |
