Abstract

To measure natural gas energy more rationally

the method of natural gas energy measurement is studied.The working principle is introduced.Natural gas energy measurement system software and hardware are designed according to energy measurement requirement.Natural gas energy measurement system is established based on natural gas internal fiber-optic network.The volume flow

component data

pressure

temperature and other parameters are read out simultaneously in this system.Natural gas energy is calculated through the internal core software according to the method of natural gas energy measurement.The system of analysis and calculation of uncertainty

the results show that the uncertainty of energy measurement could be reached 1 %（k=2）

when the measurement process is kept in good control.The result of test shows the system is easy to operate

and can load the volume flow

component data

pressure

temperature and other parameters steadily.Compared with software FLOCALC

the relative error is less than 0.1 %.
