摘　　要：介绍了钐钴永磁流量计的研制过程,包括材料选取、结构设计、运行原理及内部磁场分布状态。利用镓铟锡高温冲刷回路与商用流量计对其进行了校准比对,结果显示校准后的平均流速约为钐钴永磁流量计测量值的1.8倍。将校准后的结果运用于液态锂铅自然对流回路的流速测量,并与商业软件ANSYS Fluent模拟计算结果进行对比,二者之间的误差约为23.3%,并对误差进行了分析。通过实验与分析,确定锂铅自然对流回路的流速范围约为0.05~0.06m·s^(-1)。A development process for the samarium-cobalt permanent magnet flowmeter is presented,consisting of material selection,structure design,operation principle and internal magnetic field distribution.The calibrated average velocity by the commercial flowmeter in the gallium-indium-tin high temperature scouring loop is about 1.8 times of the measured value by the samarium-cobalt permanent magnet flowmeter.The calibrated formula is applied to the velocity measurement of lead-lithium natural convection loop and compared with the simulation of commercial software ANSYS Fluent.The error between them is about 23.3%,and is analyzed.It can be determined that the velocity range of lead-lithium natural convection loop is from 0.05m⋅s^(-1) to 0.06m⋅s^(-1) through the experiment and analysis.
