Air flow COFRAC calibration

The gas flow domain is part of the ground history of Aérométrologie, as it is one of the three accreditations in 1994. Nowaday, we propose calibrations on our two sites. The proposed calibration range is from 5 cm3.h-1 to 15000 m3.h-1, including various instrument types : Gas meter Turbine – rotary piston Insertion Flow meter Rotameters – flow liters Balometer (air capture hoods) Mass flow meter, soap bubble flow meter, Graphite piston flow meter, Differential pressure flow meters Calibrated orifice/ nozzle under a service pressure Blower-door Accreditations: Gas flow rate measurement N°2-1294(5 cm³.h-1 to 15000 m³.h-1 ), Les Ulis (91) N°2-1931 (10 cm3.min-1 to 8,5 m³.h-1 ), Pernes-Les-Fontaines (84) Scope is available on www.cofrac.fr
