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