Multi‐modality multi‐interface level sensor with segmented capacitance and inductance sensing elements

Abstract

Purpose

Crude oil separation is an important process in the oil industry. To make efficient use of the separators, it is important to know their internal behaviour, and to measure the levels of multi‐interfaces between different materials, such as gas‐foam, foam‐oil, oil‐emulsion, emulsion‐water and water‐solids. To develop a multi‐interface level sensor.

Design/methodology/approach

Multi‐modality sensor with segmented capacitance and electromagnetic sensing elements. Some key issues are addressed, including the effect of salt content in water on measurement.

Findings

Working with gas/oil/saline water, the simulation and experimental results show that the newly designed sensor is promising.

Originality/value

First time to present this multi‐modality sensor, which can cope with current problems with saline water.
