| Zusammenfassung | The technical approach for an optical primary flow rate standard based on the application of conventional LDV as well as on a new LDV-gased boundary layer sensor is presented. Both technologies are used to determine the characteristic values of the core flow and the boundary layer in a nozzle flow in a separated approach. The uncertainty of the related data processing (especially for the boundary layer) is explained in detail. After summarizing the uncertainty budget for the optical based primary standard, the approval of the new primary standard is demonstrated by means of a comparison with the established conventional traceability of PTB for high pressure natural gas. |
