The problem of how to meter oil-water-gas mixtures has been a significant one in the oil
industry since the early 1980s. Since then, considerable research has been conducted into …

Oil monitoring constitutes an important and essential component of condition monitoring
technologies and has distinguished advantages in revealing wear, lubrication and friction …

Abstract Online monitoring of Water-Liquid Ratio (WLR) in multiphase flow is key in
petroleum production, processing and transportation. The usual practice in the field is to …

We experimentally investigate vertical upward oil–water two-phase flow in a 20mm inner
diameter pipe. We first using vertical multiple electrode array conductance sensor measure …

A dual sensor tomograph for three-component flow imaging has been built at the University
of Bergen in cooperation with Christian Michelsen Research AS and Norsk Hydro AS. It …

The design methodology of capacitance sensors for void-fraction measurement in adiabatic
two-phase flow systems is presented in this paper. The effect of design parameters on the …

In the present study, we propose a parallel-wire microwave resonant sensor (PMRS) with
transmission-through configuration for water holdup measurement in high water-cut oil-in …

This paper presents the characteristics of a double helix capacitance sensor for
measurement of the liquid holdup in horizontal oil–water two-phase flow. The finite element …

Due to the complex flow structures of horizontal oil–water flows, the liquid holdup
measurement is still a challenging problem. In this paper, we using the finite element …

Efficient oil production and refining processes require the precise measurement of water
content in oil. This paper presents a novel planar microwave sensor for entirely non-intrusive …
