A new methodology for designing the differential pressure flowmeters for fluid energy carriers has been developed in order to provide the minimum uncertainty of flowrate measurement results. This methodology is implemented in “Raskhod-RU” CAD system for the computer aided design and calculation of differential pressure flowmeters. “Raskhod-RU” CAD meets the requirements of new Standards (DSTU GOST 8.586.1,2,3,4,5-2009 and GOST 8.586.1,2,3,4,5-2005).
