  • Method and device for measuring the flow rate of a fluid
    Patent number: 7127954
    Abstract: A method for measuring the flow rate of a fluid flowing in a conduit includes separating the fluid into two portions then flowing into two branches (20, 22). Both portions are then recombined in an outlet manifold (14). A difference is created between the temperature of the fluid in one of the two branches (20, 22) and the temperature of the fluid in the other branch, and the passage section for the fluid in each of both branches is modulated while maintaining the total passage section constant for the fluid in both branches so that the temperature of the fluid in the outlet manifold (14) varies in a modulated way. The temperature changes of the fluid in the outlet manifold (14) are detected versus time, and the flow rate of the fluid in the conduit is determined from the detection of temperature versus time.
