Abstract: Tendency to miniaturize all objects is spread widely in industrial sectors such as health, chemistry, automotive and electronics. Hydraulic components of the systems are also concerned and traceability to the international system of units in this domain has to be developed. Concerning liquid flow metering, several manufacturers industrialize instruments specific for small flows. On a metrological point of view, few National Metrological Institutes (NMI) are able to calibrate flowmeters with liquid at flow rate smaller than 1 l.h-1 (2,8.10-7 m3.s-1). During the last five years, LNE-CETIAT (French designated institut) has designed and built a new calibration facility to cope with this need. This paper present the concept of the calibration facility and the first results obtained with this new standard.
