Research on weight function distribution method under special boundary based on electrical characteristics

The correct solution of weight function is very important to the analysis of induced potential distribution. In this paper, the weight function under the special boundary of Laplace equation is simulated and studied. Firstly, the boundary conditions are studied by using the electrical characteristics of the electromagnetic flowmeter sensor. Secondly, the weight functions of different conductivity and thickness measuring tubes are analyzed. Finally, the analysis conclusions are verified from the perspective of experiments. The research conclusion proves the correctness and validity of the research theory based on the special boundary weight function of electrical characteristics. The analysis method in this paper is of great significance in studying the influence of electromagnetic flowmeter wall contamination and electrode contamination on the weight function.
