摘要： An apparatus, system, and method for use in determining at least one property of a flowing multiphase fluid involves comparing an initial signal and a pair of local reference signals with a set of flow characteristics extracted from reference sensor feature maps wherein the signals are related to the flow of the multiphase fluid as it passes through a flow passage which is continuously monitored, adjusted, and calibrated. Based upon the comparison, a decision is made to either resume monitoring of the flowing multiphase fluid by using a pair of local reference signals which are closely positioned and defined, or to adjust the flow passage area significantly in order to improve metering flow conditions. The invention is best suited for determining transport flow velocity and gas void fraction or relative proportions of the gas phase and the liquid phase within the multiphase fluid which subsequently can be used to quantify gas and liquid flowrates.
