摘要：
Paper presents a simple approach to a dry calibration procedure for primary transducer of electromagnetic flowmeter for open conducting and nonconducting flow channels. Author focused on two main problems: variable water level in measurement zone and variable environmental conductivity and their influence on a flow signal. Based on existing numerical model of primary transducer author described a main idea of transfer function calculation with a few examplary results. As an approximation instrument for a final form of correction function the sigmoidal two layer neural network has been applied.
