METHOD FOR RECORDING MULTI-PHASE FLOWS THROUGH A TRANSPORT SYSTEM

摘要

ABSTRACT OF THE DISCLOSUREA method for determining the flow situation in a transport systemwhere the flow medium occurs in multiphase and is conductedthrough a structural detail such as a choke valve, which acts onthe flow of the medium and produces turbulence causing acousticenergy signals which are generated in and immediately close tothe structural detail. The acoustic energy signals are sensedby one or a plurality of acoustic sensors with an acoustic broad-band connection with the structural detail. The sensor convertsthe energy signal to transmittable signals to a signal processingunit utilizing known signal analysis principles to provideinterpretable information on the actual flow situation and theflowing medium which is influenced by the structural detail. Thestructural detail to which the acoustic sensor means is connectedmay be incorporated in the subsea production system.
