Abstract

This paper deals with a problem of selecting an appropriate liquid level as a parameter in designing the exciting coil of the electromagnetic (EM) flow meter. The influence of variable liquid level on the transfer function of the EM flow meter is explained. The method of selecting the optimal liquid level utilizing the metric spaces is described. Some examples of metrics and the results of numerical calculations are presented. With this method, the transfer function of the EM flow meter can be significantly improved
