摘要
在空气气源负压法音速喷嘴气体流量标准装置使用的前提下,通过考察气体腰轮流量计的安装方式,研究了气体腰轮流量计转子自重对测量结果的影响,研究证明气体腰轮流量计转子自重对测量结果的影响量不超过0.30%。
Based on the flow standard device of sonic nozzles by negative pressure which the air was used as the gas source, the installed method of the gas waist flowmeter was investigated, andthe effect of the rotor gravity on the measurement result was studied.It is proved that the effect of the rotor gravity on the measurement result of the gas lobed flowmeter was no more than 0.30%.
