Natural gas metering plays an important role in natural gas management,and its accuracy and reliability are directly related to the interests of both natural gas supply and demand.In practical application,due to the role of many factors,natural gas measurement may produce errors,which will not only affect the accuracy of measurement,but also bring economic losses to both the supply and demand sides.Therefore,how to reduce the error of the transmitter in natural gas trade measurement is the top priority of the current work.In this paper,the natural gas trade measurement is summarized,the causes of error in natural gas trade measurement are analyzed,and the error optimization strategy of transmitter in natural gas trade measurement is proposed.
