摘　　要：针对组合阀式转子流量计修正压力测点的位置进行了讨论,提出了新的修正压力测点,并对各测点进行了测量。结果表明:新的修正压力测点(在流量计上游和流量调节阀之间的直管段上某一点)的选取比较合理,且由新测点压力修正得到的体积流量比由下游压力修正得到的体积流量更接近真实值。Modified pressure point of rotometer with combined valve were discussed.A new modified pressure point was advance,and the pressure of points were measured.The results show that the new modified pressure point（between upstream of rotometer and regulating valve）is reasonable.The volume flow-rate obtained by the new modified pressure point is closer to the truth value than the volume flow-rate obtained by the downstream pressure point.
