| Zusammenfassung | To quantify the equivalence of water flow measurement standards maintained in National Metrology Institutes (NMIs) key comparisons (KC) are performed, in which participating NMIs can compare their performance through their calibration data. The quality of the KC is highly correlated with the behaviour of transfer standards to different installation effects, operating conditions, etc. The purpose of this bilateral comparison is to find the best available transfer standard for the upcoming KC of the water flow measurement standards (CCM.FF-K1.2015). Therefore, the performance of the three different flowmeters in two different facilities was compared, in order to realize if these flowmeters are suitable as transfer standards for the KC. A turbine and two coriolis flowmeters were used in this project. Each country performed the calibration using their regular calibration procedure. PTB was the pilot laboratory for this bilateral comparison, due to the fact that PTB also serve as a pilot laboratory for the key comparison CCM.FF-K1.2015. Additionally, the CMC entrance of both facilities were investigated by a comparison of the used meters. |
