The study of electrode size on sensitive field effect of electromagnetic flow meter in the measuring fluids containing non-conductive body

摘要

Electromagnetic flow meters are widely used in two-phase or multi-phase flow measurements in recent years. In this paper, simulation model is established to study the flow meter response characteristics which exist a non-conductive body (oil bubble) in the fluid by use finite element software ANSYS. We analyze different electrode size impact on the response characteristics of electromagnetic flow meter in the measurement of two-phase or multi-phase flow which includes non-conductive material in the fluid, which provides reference for design of the sensor electrode sizes, and provides a theoretical basis for error analysis measuring two-phase or multi-phase flow under different electrode sizes of electromagnetic flowmeter.
