摘　　要：给出了不同电极数目下电磁流量计权重函数的仿真结果.权函数表示流动横截面上特定空间位置上的流体速度对流量计输出信号的相对作用.权函数的求解对根据电磁流量计测量的电位差来推断速度分布是很重要的.通过对比不同数目电极下权重函数的分布,可以得出,电极数目越多,对流型的敏感度越小,从而可以实现对非轴对称流流量准确的测量.this paper gives the results of the electromagnetic flowmeter weight function under the number of different electrode the simulation.Weight function said flow cross section,particular space on the fluid velocity of flow meter output signal to the relative effects.the solution of weight function of electromagnetic flowmeter measurement according to the conductor to infer the velocity distribution is very important.Through comparing the different electrode,the weight function under the number of distribution,it can be concluded that the convection,the number,electrode type,and the more the sensitivity of the small can realize to the axisymmetric flow accurate measurement.
