In order to meet the requirements of large diameter pipeline sodium flowmeter in reactor engineering,a large diameter sodium flowmeter based on series structure was studied by using electromagnetic software ANSYS Maxwell.The designed large diameter pipeline sodium flowmeter is composed of two magnetic steel in series,which can be used to measure the liquid sodium flow of 150mm pipeline.By analyzing and adjusting its key dimension parameters,a large diameter sodium flowmeter with good uniformity and strong magnetic induction is obtained.The results show that,magnetic induction intensity simulation results are in good agreement with the measured results,and the simulation model adopted is correct.The designed large diameter pipeline sodium flowmeter can meet the large flow measurement requirements of engineering pipelines,and has certain reference significance for the subsequent design of large diameter pipeline sodium flowmeter.
