Abstract: Test rigs with small sonic nozzles are widely in use for the verification of domestic gas meters. The typical flow rates range from 10 l/h to about 40 m3/h. In the past, the test gas was air in nearly all of the commercial applications. This was sufficient as long as the domestic meters could be tested and verified with air. But nowadays the market faces the introduction of new technologies, especially meters using the so-called thermal mass flow elements. Meters based on this technology require the use of calibration gas which has to be as similar as possible with the gas in application. Otherwise a correct adjustment and verification cannot be confirmed. The application of small sonic nozzles down to 10 l/h in test rigs with natural gases asks for the consideration of new things concerning the correct traceability within the required uncertainties:
