| Zusammenfassung | This year the construction has started of the new Closed Loop pigsar (CLP) facility. The new facility can be operated parallel to the pigsar bypass facility, which has a reliable track record of almost 25 years. The expanded measurement capabilities of the new CLP require the present traceability chain to be extended. The current study confirms the feasibility of the projected CMCs of the new Closed Loop pigsar. In addition, the work on a shorter traceability chain has started. A new primary standard is being developed which can be directly connected to the CLP. A new transfer standard will allow quicker calibrations of the CLP references. The use of multiple independent traceability chains will improve measurement uncertainties of high-pressure flow measurements, similar to the harmonized cubic metre. The new CLP will enable PTB / pigsar to participate on the intercomparisons at 8 bar pressure and up to a flowrate of 6500 m³/h at all pressures. This will give a broader fundament to the harmonized cubic metre. |
