Computer-aided designing the natural gas energy metering systems based on differential pressure flowmeters

The paper presents the computer-aided design system for developing the natural gas energy metering systems based on differential pressure flowmeters with standard primary devices. The main characteristics of CAD subsystems are presented. CAD makes it possible to calculate the natural gas energy amount for the specified characteristics of measuring instruments and the flow parameters of heat carrier and to use these values as reference while testing the existing metering systems.
