1. A method for monitoring fluid flow in a conduit, the method comprising:

  • acoustically coupling an optical fiber to the conduit adjacent to a flow restriction in the conduit;

    inducing a Distributed Acoustic Sensing (DAS) assembly to measure an acoustic noise signature generated in the optical fiber by the fluid flowing through the flow restriction;

    deriving the fluid flow rate of the fluid flowing through the flow restriction from the measured acoustic noise signature; and

    displaying the derived fluid flow rate at a fluid flow rate monitoring display.
