Multiphase flow measurement system and method

A multiphase flow measurement system, comprising:

• a first video head assembly having at least one video head disposed at a first location along a conduit;
• a second video head assembly having at least one video head disposed at a second location along the conduit, the first location and the second location being separated by a known distance, the first location and the second location having a transparent portion allowing the first video head assembly and the second video head assembly to video record contents of the conduit flowing through the first and the second locations;
• a first adjustable illumination source illuminating contents of the conduit flowing through the first location;
• a second adjustable illumination source illuminating contents of the conduit flowing through the second location;
• a processor operably connected to the first and second video head assemblies, the processor receiving and processing video frames from the first and second video head assemblies, respectively, the processor having:
• means for isolating image objects related to phases of a fluid flowing in the conduit captured in image frames taken by the video head assemblies;
• means for separating image objects by phase into object classes;
• means for cross-correlating the object classes from the first location with the corresponding object classes from the second location;
• means for detecting delay time between the object classes in the image frames;
• means for calculating flow speed of the object classes through the conduit based on the delay time;
• means for calculating an aggregate speed of each of the phases based on the object classes associated with the phases;
• and
• means for determining the flow speed and the flow type of the phases by aggregation of the aggregate speeds of the phases.
