| Zusammenfassung | For almost 25 years the high-pressure calibration facility pigsar™ in Dorsten, Germany, has been operated in a so-called bypass configuration. Changing customer requirements and worsening conditions provided by the high-pressure gas network make it necessary to enlarge the capabilities of pigsar™. It was decided to construct a new Closed Loop pigsar (CLP) calibration facility. This new facility will be operated in parallel and close to the existing facility for gas meters over 12" diameter, while it is intended to calibrate the gas meters below 12" at the existing facility. One of the key performance parameters of a test facility is its measurement uncertainty. Therefore, special care has been taken during design and planning of the new facility as well as for the modus operandi of the CLP to achieve low uncertainties. This especially regards the design of the traceability chain of the new CLP, the modelling of the calibration processes and the development of a new primary standard by PTB. Evaluations by PTB have shown that measurement uncertainty can be improved quite considerably by combining several traceability chains currently developed and improved by PTB.
