EUREGA-1

Project Description (Update 2021-05-10)

In 1999, Germany and the Netherlands agreed on the establishment of a harmonised reference for high-pressure gas flow measurements to enhance the metrological base for transnational trade of natural gas in Europe. Since 2013, EuReGa is the name under which the National Metrology Institutes and Designated Institutes of Germany, the Netherlands, France and Denmark cooperate. The Harmonized Reference Value (HRV) is based on multiple independent traceability chains. The HRV is the weighted average obtained via an intercomparison procedure, applied for the first time in 1999 and updated in 2018. The laboratories change their own reference values to the HRV and benefit from a reduction of measurement uncertainties. This procedure is successful as long as the stochastic contributions to the overall measurement uncertainties are significantly smaller than the uncertainties arising from the traceability chain.
