Non-invasive measurement of oil-water two-phase flow in vertical pipe using ultrasonic Doppler sensor and gamma ray densitometer

• A method of measurement flow velocity in oil–water two-phase vertical using a non-invasive ultrasound Doppler sensor is developed. We present correlations for both oil-continuous and water-continuous flow. formulated the drift-flux model estimation superficial oil water from measured velocity. The estimated results this proposed are good agreement with reference flowmeters. Oil–water experiments were conducted pipe to study liquid–liquid gamma-ray densitometer. Tap dyed mineral used as test fluids. novel effect strategy estimate mixture based on by shear profile model. Drift-flux was conjunction phase fractions predict velocities water. indicate that have average relative errors 5.2% 4.5%; 4.5% 5.9% respectively. These demonstrate potential ultrasonic combined gamma densitometer measurement.
