摘要
文章提出采用负压pVTt法气体流量标准装置检定高精度气体流量计,并从理论层面分析了负压pVTt法气体流量标准装置检定气体流量计的可行性.主要包括检定装置的不确定度评定、工作原理、检定流量范围、检定时间和存在的难点等几个方面,重点为解决高精度流量计无法检定溯源的难题,为高精度流量计检定装置的建立奠定基础.
Abstract
This paper proposes to verify high-precision gas flowmeter with calibration facility to pVTt technique,and analyzes the feasibility of gas flowmeter calibration with calibration facility to pVTt Tech-nique.It mainly includes uncertainty evaluation,working principle of the calibration facility,flow range which can be verified by the calibration facility,calibration time required to verify the flowmeter and ex-isting difficulties and so on.It focuses on solving the problem that the high-precision flowmeter can't be verified,and lays the foundation for the establishment of the high-precision flowmeter calibration facility.
