Study on Fusion of Electromagnetic Flowmeter and ERT System in Slug Flow

摘要

Based on the theory of electromagnetic induction flow measurement under the condition of slug flow,the functional relation equation between output potential of electromagnetic flowmeter and flow parameters is studied,established and deduced. Then the theoretical equation of fusion of electromagnetic flowmeter and electrical resistance tomography (ERT) that is used to the parameters measurement of slug flow is obtained.It provides a new method for parameters measurement of two-phase flow.
