摘要： 研究了不同组合双钝体的仪表系数流量关系，通过压力损失分析，得到线性度及压力损失皆佳的一组钝
体组合． 给出了多种钝体组合结构的仪表系数及压力损失试验结果，表明双钝体结构在一定的流量范围内具有类
似单钝体的常定斯特劳哈尔数．

Abstract: The relation between the meter factor and flow rate for various dual bluff body combinations is investigated．A set of bluff body combination with an optimal performance of linearity and pressure loss is achieved through the pressure loss analysis．The experimental results of meter factor and pressure lOSS are also presented． The results show that the dual bluff body combination can have a similar constant Strouhal number to the single bluff body in the specific range of the flowrate．
Key words: vortex flowmeter    meter factor    linearity    bluff body combination
