Bilateral hybrid comparison: High flow rate water - 150 t/h to 1200 t/h

Project Description

VSL recently commissioned a new high flow rate water calibration facility (WF2500) within its European Center for Flow Measurement. This facility has a maximum flow rate of 2500 t/h flowing through four Coriolis master meters in parallel. The traceability for this system is based on the direct mass comparison of the individual Coriolis meters to VSL’s existing 10t scale up to 500 t/h and a bootstrap calibration process building above 2000 t/h up to 2500 t/h. 

The purpose of this Bilateral Comparison (BC) for “High flow rate water” measurement is to support the Calibration and Measurement Capabilities (CMC) of the new water flow facility at VSL as part of the CIPM MRA.

The aim of the comparison should lead to ‘a clear and unequivocal’ comparison of measurement results between VSL (Netherlands) and PTB (Germany).

The results will be sent to Elsa Batista from IPQ (Portugal) who will act as the third party.
