| Zusammenfassung | For the first time in the history of high-pressure gas flow measurements a reference system has been realised that consists of three metering technologies: turbine gasmeters, Coriolis meters and sonic nozzles. The system is designed for the calibration of flowmeters using different gases and gas mixtures. The models for the discharge coefficients and the turbine gasmeters compensate the different thermodynamical properties of the gases and gas mixtures. For this reason, the system works independently of pressure and gas composition. The mass flowrate of the reference system is the uncertainty-weighted average of all three meter types. As the three instrument types have completely independent traceability chains, the measurement uncertainty of the average flowrate can be calculated in the same way as the common reference value in intercomparisons. The resulting uncertainty of 0.12% meets the best available CMCs in the high-pressure calibration market. |
