Abstract: A method for monitoring fluid flow in a conduit comprises: acoustically coupling an optical fiber to the conduit adjacent one or more flow restrictions (R1-R4) in the conduit; inducing a Distributed Acoustic Sensing (DAS) assembly to measure an acoustic noise signature (SNR1-4) generated in the fiber by the fluid flowing through each flow restriction (R1-R4); deriving the fluid flow rate of the fluid (QI, QI+II) flowing through each flow restriction (R1-R4) from the measured acoustic noise signature (SNR1-4); and displaying the derived fluid flow rate (QI, QI+II) at a fluid flow rate monitoring display.
