| Zusammenfassung | Since 1993 E.ON Ruhrgas operates pigsarTM as one of the leading high-pressure gas calibration facilities worldwide. One major prerequisite for pigsar™'s very low uncertainty is the fact that the German national volumetric primary standard for high-pressure natural gas, the so-called High Pressure Piston Prover (HPPP), property of the Physikalisch-Technische Bundesanstalt, (PTB), is since 1999 an integral part of the infrastructure of pigsar™. During the last few years both PTB and pigsarTM staff have continuously worked on improving the uncertainty and availability of pigsar™. As a major result, the uncertainty of pigsar™ was reduced from initially 0,16% to currently 0,13% in the main operating regime of the facility. New projects already started are aimed at reducing this uncertainty even further down to 0,1%. This paper describes the different measures that have been or will be taken to achieve and verify these improvements. |
