  • Flow meter
    Patent number: 4006634
    Abstract: A flow meter includes a variable area obstruction mounted in a conduit and a differential pressure transducer having its two ports mounted on opposite sides of the obstruction in fluid communication with the fluid flowing through the conduit. The variable area obstruction is formed of one or more flexible leaves which extend into the flow stream and are deflectable under the influence of fluid pressure, such that an increased flow rate increases the deflection of the leaves and decreases the area of the obstruction.
