Computer Aided Design of Differential Pressure Flow Meters
Abstract: New methodology of designing the differential pressure flow meters for fluid energy carriers is developed in order to provide minimum uncertainty of results of flow rate measurement. This methodology is implemented in “Raskhod-RU” CAD system for computer aided design and calculation of differential pressure flow meters. “Raskhod-RU” CAD meets the requirements of new Standards implemented in CIS countries (GOST 8.586.1,2,3,4,5-2005) and provides accomplishment of the following tasks: verification of conditions (constraints) for application of the differential pressure method according to the requirements of new Standards; calculation of parameters of primary device, pipe straight lengths and flow meter in general according to the requirements of new Standards; calculation of uncertainty of results of fluid flow rate and volume measurement.
