本实验室选用干活塞气体流量标准装置作为标准器,对热式气体质量流量计进行示值误差测量。本文考察了校准过程中的各个环节,分析了质量流量计示值误差的测量不确定度来源,对流量示值误差的测量不确定度进行评价。
A dry piston gas flow prover was used for measuring indication error of thermal mass gas flowmeter.The sources of measurement uncertainty of gas flowmeter indication error were analyzed in the calibration process,then the measurement uncertainty was evaluated.
