Abstract:
1. A method of providing measurements relating to different phase components of a flowing fluid, wherein an entire phase range from 100% liquid flow to 100% gas flow can be measured, the method comprising: obtaining at least one input representing a velocity of flowing fluid produced by a Doppler measuring device and/or a Time of Flight measuring device non-intrusively/externally mounted on a conduit containing the flowing fluid; using the at least one velocity input to calculate a total volumetric flow of the flowing fluid; obtaining measurements representing density of the flowing fluid; using the velocity input and the calculated total volumetric flow to compute, using a computing device, a volumetric flow of a gas component of the flowing fluid using a formula: where the base density is calculated using the formula: providing individual phase components of said flowing fluid as separate outputs based on the computed gas volumetric flow.
