Abstract: The invention makes it possible to measure, in real time, the flow of a fluid that is incompressible while having an unsteady flow. The pressure measuring system is primarily comprised of a negative-pressure element (1) placed within the flow and provided with two wall pressure taps (A, B). A means (2) for measuring a pressure difference connected to the pressure taps (A, B) enables the following formula to be solved: dq(t)/dt+?(q(t))=?×?p(t) directly stemming from fundamental equations of fluid mechanics and/or: ?p(t) represents the pressure difference measured by the sensor; q(t) represents the sought volume flow rate, and; ? represents a function of the geometry of the negative-pressure element, of the fluid and of the flow q(t), the particularity of this formula being the consideration of the direction of flow in the second term of the left member of the formula.
