In order to detect extremely low gas transmission rates through a sample, it is necessary to abandon direct flow measurement because flow meters are not very accurate. Diffusion Permeameters determine the low gas flow rates indirectly by measuring time rate of change of pressure on the outlet side. The sample was loaded in the sample chamber which divides in two chambers. One chamber is on the ...
