Multielectrode inductance flowmeters were brought forward toward coping with the problem of flow regime dependence of traditional inductance flowmeters. Design of the electrode array is of great importance in construction of a multielectrode inductance flowmeter. The number of electrodes and electrode size are two primary parameters of the array. In this paper, the governing equation of the multielectrode inductance flowmeter was solved using a finite difference method. The chord measurement method was employed to analyze the influences of both parameters on the estimation of mean flow velocity. Based on the quantitative calculation of the influences of the two parameters on measurement error, criteria for the design of the electrode array were presented.
