The aim of this paper is to provide a comprehensive review of the current measurement
technologies available for on-line monitoring of the performance of the gas/oil/water …

Ultrasound reflects strongly off the gas–liquid interface when there is a large change in
acoustic impedance. We exploit this phenomenon to detect the instantaneous position of the …

The combined use of ultrasound pulse-echo intensity and Doppler shift frequency is
examined as a means to measure strong unsteady three-phase pipe flows of a gas and two …

Air–water two-phase flow in a helically coiled tube is investigated using backlight imaging
tomography to elucidate the effect of centrifugal acceleration on phase distribution and …

X-ray computed tomography (CT) is used to explore the differences in a semi-batch bubble
column operated at superficial gas velocities of Ug= 3, 10, and 18cm/s. Air–water or air …

Multimodality sensing is used for monitoring of multiphase hydrocarbon flow where there is
a need to measure the quantity of oil, water and gas in a cross section of a pipe originating …

This paper proposes an intrusive method for measurement of water holdup based on water
layer thickness in horizontal pipes. Water layer thickness is measured by a capacitance …

Multiphase flow assurance in oil and gas upstream industries covers a wide range of flow
conditions. Over the last decade, the investigations and developments of multiphase flow …

With the advantages of non-invasion, non-radiation, low-cost and high-speed, electrical
resistance tomography (ERT) is suitable for online measurement of multiphase flow inside a …

Backlight imaging tomography is used to experimentally investigate interfacial structures of
gas–liquid two-phase flow in circular tubes. The tomography method is based on the …
