Abstract

Electrical capacitance tomography (ECT) is a technique developed in recent 30 years, which aims to measure multi-phase flow. The image reconstruction for ECT is an inverse problem to find the permittivity distribution in a pipe. The normalized capacitance measurements are needed during the process of image reconstruction. Parallel normalization model is the most commonly used normalization model, and series normalization model was also studied by some researchers. In this paper, a mixed normalization model based on electrical field center line (EFCL) and multi-threshold method was presented. The sensitivity matrices based on different normalization models were obtained and image reconstruction was carried out accordingly. Simulation and static experiment indicate that reconstructed images with higher quality can be obtained based on the presented model.
