ABSTRACT:
A system determines the relative amounts of phases in multiphase flow, typically the liquid (or gas) fraction of a stream in two-phase flow. More particularly, the system quickly and reliably determines the liquid (or gas) fraction of a flowing two-phase stream, such as a process stream commonly found in chemical processing or in petroleum production operations. The system yields accurate results regardless of the exact flow regime under which the two-phase stream is flowing.
