| Zusammenfassung | In this paper the model is derived which describes the processes of liquid flowmeter calibration and its utilization in meter applications. Subject of uncertainty analysis is the gravimetric calibration facility with the so-called flying-start-and-finish approach. The hydrodynamic test field at PTB Braunschweig the national metrology institute (NMI) of Germany, is representing such a type of liquid flow calibration facility. It provides high accuracy for liquid flow measurands mean volume flow rate and totalized liquid flow. The calibration of a liquid flowmeter can only take into account meter characteristics under ideal flow conditions. Conditions occurring in flowmeter applications may be different from those in the calibration facility and, thus, contribute additional uncertainty effects. The proceedings are also available on CD-ROM. |
