In this paper, the electromagnetic flowmeter and the image processing are used to measure
vertical gas-liquid two-phase flow. In order to reduce the effect of randomly distributed …

Oil–water two-phase flow experiments were conducted in a vertical pipe to study the liquid–
liquid flow measurement using a non-invasive ultrasound Doppler flow sensor and a gamma …

A flow velocity measurement method based on continuous wave ultrasound Doppler
(CWUD) and flow profile modeling is presented. A theoretical model is proposed to relate …

When the oil field has been exploited by long-term water-flooding, it will be in high water-
content stage of production. However, it is a great challenge for high-water-content …

Oil-water two-phase flow is the main fluid form in petroleum industry. Since it is associated
with safety operation and economic benefit, the flow velocity needs to be measured …

In the present study, an accurate cost-effective online system for metering both the gas flow
rate and the liquid flow rate in wet gas with only one V-Cone throttle device is developed …

A novel on-line, contactless and nearly non-intrusive measurement method based on
thermal diffusion is proposed for gas–liquid slug flow in this paper. Temperature fluctuations …

This research investigates the effects of flow pattern and salinity of oil-water two-phase flow
on water holdup measurement using a conductance method. Firstly, vertical upward oil …

A combination of ultrasonic transducers operated in continuous mode and a conductance/
capacitance sensor (UTCC) is proposed to estimate the individual flow velocities in oil …

We present an approach based on computer vision and machine learning methods to
identify two-phase flow with complex flow patterns in oscillatory conditions. A visualization …
