Utendo principii differentialis pressionis methodi, specimen prae-processum ponitur inter superiores et inferiores superficies metiendi et constantem pressionem differentialem ex utraque parte exempli formatur. Sub actione pressionis differentialis, gas per exemplum fluit a parte alta pressura ad latus depressum. Secundum aream, pressionis differentialis et rate fluit exemplum specimen, permeabilitas exempli computatur.
