Abstract

A key comparison of the gas flow standards of the National Insititutes of Metrology was conducted from December 2010 to December 2012. A rotary gas meter type Delta S-Flow G 65 was selected as transfer standard. Laboratories were compared in low pressure gas flow in the range (2 - 100) m³/h. Eleven NMIs took part in this key comparison and the KCRV was determined. The results demonstrated degrees of equivalence to the KCRV. Euramet comparison were organised simultaneously with the same transfer standard. Sixteen NMIs took part in this regional comparison. Regional reference value was determined also as link to the key comparison. The presentation reports information about the results in comparisons CCM.FF-K6.2011 and EURAMET No. 1180.
