Abstract:
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.

Claim (Index 1):
A system for use in determining a property of a flowing multiphase fluid comprising:\n (a) an apparatus comprising:\n (i) a body comprising an entrance for directing the multiphase fluid, and an exit for discharging the multiphase fluid and defining a flow passage between the entrance and the exit for directing flow of the multiphase fluid therethrough; \n (ii) a flow diverter assembly comprising a stationary housing disposed downstream of the entrance; and a movable flow diverter movable towards, within, or away from the stationary housing, the stationary housing and the movable flow diverter together defining a metering flow area and guiding the flow of the multiphase fluid towards and out of the metering area, the movable flow diverter being coupled to a displacement assembly for positioning the flow diverter towards, within, or away from the stationary housing; \n (iii) at least one monitoring device mounted in fluid communication at a measurement point for monitoring the property of the multiphase fluid flowing therethrough; and \n (b) a controller communicatively coupled to the at least one monitoring device for calculating the property of the multiphase fluid from at least two signals received from the at least one monitoring device.
