PTB's "Hydrodynamic Test Field"-Investigations to Verify the Measurement Uncertainty Budget

Rainer Engel

Abstract

Establishing a national liquid flow standard that meets the accuracy requirements of modern industry makes necessary the application of up-to-date instrumentation devices in a calibration facility and appropriate test and verification procedures applied on this facility. The participation of PTB's new water flow facility in the international key comparison test of the CIPM; CCM.FF-K1, provided the opportunity to utilize the approved round-robin transfer standards in order to prove the accuracy, repeatability as well as the stability of the essential process parameters during the measurement and calibration procedures.
