Abstract

The subject investigated of this paper is major in the ECT system of 8-electrode oil-water two-phase flow, and the measuring principle is analyzed, the mathematic model of the oil-water two-phase distribution information is established based on double integral infinitesimal principle, an ECT measurement system of 8-electrode oil-water two-phase flow is set up. At the same time we present the method of image reconstruction to accomplish the concentration measurement of oil-water two-phase flow. Based on ART image-reconstruction algorithm, we present threshold value to improve quality of image reconstruction and calculating accuracy of content and the precision of reconstruction is about 1%, which can meet the need of identification of flow regime for oil-water two-phase flow.
