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.
