    This article describes a primary calibration setup and its uncertainty for low flow liquid calibrations at Bronkhorst High-Tech, which is traceable to international standards. It will be used to calibrate reference flow meters from 1 to 200 g/h. By setting up an uncertainty budget for this setup, the calibration of the instruments will be traceable. The uncertainty budget consists of mass, time and mass flow uncertainties/corrections that need to be taken in account for determining the real mass flow. By participating in an laboratory intercomparison the accuracy and calculated uncertainty of this setup is traceable to international standards at several European national metrology labs.
