Summary In this paper, a brief history review of works on the theory of electromagnetic flowmeters is given. A method named'Alternative iteraction method for approaching real boundaries'is presented to solve Laplace's equation with mixed boundary conditions in electromagnetic flowmeters. The orthogonal expansion is used to analyze weight vectors and flow distribition effects on the sensitivity of the flowmeters.
