The flow coefficients of the orifice-plate flowmeters are experimentally studied with or without a rectifier at the lower reach of a space elbow in the measuring pipe of flow.
通过实验研究，观察分析了流量测量管路中空间弯头下游有(或无)整流器时对孔板流量计流量系数的影响。

Clearly, the effect of this must be taken into account when the orificeplate dimensions are determined.
显然，这种效果，必须考虑到当孔板方面的决心。

This paper presents the significance and method of correcting the sharpness of standard orificeplate and gives some suggests for carrying out this work.
