| 摘要 |
Embodiments of the present invention provide for measuring flow properties of multiphase mixtures within a pipe carrying hydrocarbons. Embodiments of the present invention use differential pressure measurements of multiphase mixtures flowing in phase-separated flow regimes to analyze characteristics of a liquid phase of the multiphase mixture. The phase-separated flow regimes may be provided by flowing the multiphase mixture in a substantially horizontal pipeline or swirling the multiphase mixture. The combination of differential measurements with measurements from other sensors, such as ultrasonic sensors, microwave sensors, densitometers and/or the like may provide for multiphase flow measurements, such as flow rates of the different phases or determination of the speed of sound.
