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 …

Oil-water two-phase flow commonly exists in many industries. The accurate measurement of
flow velocity is beneficial for safety operation and economic efficiency. A combination of a …

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 …

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 …

Ultrasonic techniques have been widely used to determine the volume fractions of liquid
components in oil–water two-phase flow. The two major ultrasonic interactions amenable to …

Oil-water two-phase flow exists widely in many industries. Accurate measurement of flow
velocity is of significance for quantify the volume or mass flow rate as well as monitor the …

Oil-gas-water three-phase flow is the most commonly seen fluid in petroleum production and
transportation process. Flow velocity measurement of each individual phase is important to …

Oil reservoirs with low permeability and porosity that are in the middle and late exploitation
periods in China's onshore oil fields are mostly in the high-water-cut production stage. This …

The oil–water two-phase flow experiment was carried out in a vertical upward pipe to study
the responses of the pulsed ultrasonic sensor and vertical multiple electrode array sensor …

Phase fraction of oil–water two-phase flow is important to the process control and
optimization. In this paper, a prediction model based on the mechanism of ultrasound …
