    There is an increasing demand for ISO/IEC 17025:2005 accredited liquid flow calibrations in the range of 1 g/h to 30 kg/h. The accredited Low Flow liquid Calibration Setup [1] (LFCS) at Bronkhorst® covers a flow range of 1 to 200 g/h, leaving a traceability gap in the flow range of 0.2 to 30 kg/h. By extending the calibration setup with two new balances it can perform calibrations from 1 g/h to 30 kg/h, thus covering the traceability gap. Crosschecks between references show good consistency and the setup extension was successfully accredited for ISO/IEC 17025:2005 calibrations. By participating in an intercomparison with National Metrology Institutes (NMI’s) the uncertainty of the LFCS extension is traceable to European NMI’s.
