Transfer Standard

Bronkhorst mini CORI-FLOW regular M12 and M13 Coriolis mass flow meters have been successfully used as the Transfer Standard between all laboratories! The instruments are now available for National Metrology Institutes as proven stable Transfer Standard for low liquid flow calibrations.

Intercomparison flow standards

Within MeDD various primary standards are developed for the calibration of infusion devices and flow meters. These standards, or calibration facilities, have been developed for liquid flow rates at ambient pressure and temperature. The flow rate range per standard varies somewhat; the combined flow rate range is between 1 nl/min up to 10 ml/min.

Goal of the intercomparison is to validate the various standards by means of comparing the calibration result for a so-called transfer standard. This transfer standard (in this case a flow meter based on the Coriolis principle) is calibrated by all labs after which the calibration results are compared. Four labs of the MeDD consortium already participated in the intercomparison, however now also VSL and Bronkhorst participated as a supplement of the main intercomparison. These measurements show that the standards of VSL and Bronkhorst are consistent with the harmonized value earlier found.
