Abstract
This paper presents an uncertainty analysis for the CEESI Iowa natural gas calibration facility. This facility calibrates flow meters up to flows of 10.7 actual m3/s, at nominal pressures of 174 kPa. Flow meters are calibrated by a set of nine turbine meter standards that are ultimately traceable to NIST. The analysis shows that the facility can achieve an uncertainty ranging from 0.28 to 0.30% at a 95% confidence level depending on flow.Citation
