Measurement of water concentration of oil–water mixtures in a pipeline is important in the oil
industry. Capacitance, γ-ray and ultrasonic techniques have been developed for the …

A three-channel conductance probe has been proposed to measure the water holdup in oil-
in-water flows with low-flow rate and high-water cut. The probe consists of three pairs of arc …

To be able to deduce water holdup from the mixture conductivity measured by conductance
sensors in water continuous oil–gas–water three-phase flow, the water conductivity must be …

In the oil industry, it is important to measure the water fraction in liquid hydrocarbons in oil
pipelines for optimising operation and transportation, eg loading/unloading of oil tankers …

In order to have on-line measurement of water content in heavy fuel oil (HFO), the so-called
water-cut meters are used. Typically, measurements performed by these devices are based …

Water holdup in crude oil-water flows is a crucial parameter to identify flow patterns or
monitor the flow process in oil production. It has been increasingly important to accurately …

A water-in-oil monitor has been developed which is suitable for monitoring water content in
older producing fields, water content in the crude from separators, and water content in …

The output response characteristics, spatial sensitivity distribution, spatial filtering effect and
frequency response characteristics are important parameters influencing the accuracy of …

A sensor system for the study of an oil-water flow in a pipe is proposed. The purpose is to
estimate the area fraction occupied by each fluid in a given section of the pipe, taking …

This paper presents a non-contact U form multi-functional sensor for the oil pipeline flow
measurement. Totally four thin and narrow copper plates are twined on both sides of the …
