The Laboratory of Gas Flow realizes the unit of gas flow in facilities comprising of several commercial primary volumetric flow devices. All gas flow devices are working with clean, dry, compressed air up to 4 bar and upon request pure nitrogen can also be used. The gas flow laboratory provides calibration and testing services for all basic gas flow metering devices in the flow range from 0.5 l/h to 430 l/h and from 1 m3/h to 130 m3/h, respectively, with relative uncertainties better than 0.2%. All primary gas flow facilities are traceable to NMi (The Netherlands) and NIST (USA).
