Abstract: | A set of Critical Flow Venturis (CFVs) were manufactured by Flow Systems and calibrated by NIST in Gaithersburg, MD. Subsequently
these flow standards along with pressure and temperature standards have been integrated into a gas flow meter calibration
(GFC) system. Performance data and an uncertainty analysis is discussed here in this paper. Calibration data on these CFV
standards will be used to inter-compare the NIST and CEESI primary facilities. |
