Abstract

This paper introduces a new approach for the parameter measurement of fluid conductivity in an electromagentic flow-meter. Based on dual excitiation method, one magnetic excitation is used for flow rate measurement, and the other electric excitation is for fluid conductivity measurement. Dual-frequency electric excitation is employed to get fluid conductivity in a wide range with high precision. A calculation model for fluid conductivity is proposed.
