Theoretical analysis of the feasibility of gas flowmeter calibration with calibration facility to pVTt technique
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.
