本文主要介绍在按照检定规程要求用钟罩式气体流量标准装置对浮子流量计开展检定时,对被检浮子流量计进行不确定度分析。主要从标准器引入的不确定度、被检计量器具分度值、气体流量温度及压力补偿方面考虑,对被检浮子流量计测量结果不确定度来源进行了较为深入的分析,可以作为以后的浮子流量计检校工作的参考。
This article mainly introduces the uncertainty analysis of the inspected float flowmeter when it is used to calibrate the float flowmeter with the bell-type gas flow standard device according to the requirements of verification procedures. Mainly from the introduction of the standard instrument of uncertainty, was seized measuring appliance division value, the gas flow temperature and pressure compensation considerations, the uncertainty of the measured floating-point flowmeter measurement of the source of a more in-depth analysis can be used as the future Reference for the float meter calibration work.
