摘要
通过标准表法气体流量标准装置的研制,对孔口流量计的流量和压力修正项之间的关系进行线性拟合,得到流量计的标准曲线并评价其准确度等级。实验结果表明了校准方法的可行性和可靠性。
A gas flow standard facility by master meter method is developed for orifice flowmeter calibration. Through the linear fitting between flow and pressure correction term of orifice flowmeter, the lfowmeter standard curve and its precision are obtained. The experiments show the feasibility and reliability of the calibration method.
