Starting with the basic principles of the weight function related with the electromagnetic flowmeter(EMF), the modeling and the theoretical analysis of the weight function in open channels are proposed, and three main respects which affect the weight function of the EMF in open channels, including the model of the electrodes, the flow liquid level and the shapes of cross sections, are emphasized employing the finite element simulation technology. The distribution characteristics and the statistical properties of the weight function are studied and the conclusions are given, which fill the blanks in the field of the basic research on the weight function in open channels.
