Title
(EN) MEASURING FLOW RATES OF MULTIPHASE FLUIDS
(FR) MESURE DE DÉBITS DE FLUIDES MULTIPHASES
Abstract
(EN)
Embodiments include a multiphase flowmeter system (300). The multiphase flowmeter system (300) may include a first inline flow conditioner (310) for reducing a slip velocity between a liquid phase and a gas phase of a multiphase fluid, a flowmeter for measuring a flow rate of the multiphase fluid, a second inline flow conditioner (350) for separating the liquid phase and the gas phase of the multiphase fluid, a non-radioactive sensor system for measuring one or more of a gas void fraction of the multiphase fluid and a water-cut of the multiphase fluid, and a processor (480) for computing one or more flow rates of the multiphase fluid. Embodiments further include methods of measuring one or more flow rates of a multiphase fluid and other related methods, apparatuses, devices, and systems.
