Caused a large waste of manpower and material resources. Along with the progress of the times, the development of information, and in order to adapt to the reform of the gas system, increase gas use information, convenient to people, which makes the study of the research and development of project information intelligent gas meter imminent. The use of gas meter control system using gas, have been greatly improved from the management department of the financial pressure, tedious work and public dispute etc. Not only can improve the work efficiency, but also can reduce the waste from the technical level and more reasonable utilization of coal gas resources. Thus, the intelligent gas meter is widely used. This design is mainly to explore the intelligent gas control system based on AVR16 MCU, as the core, to achieve read switch IC card information control valve for gas sensor, using the correct measurement of gas flow, the transmission of digital pulse sampling, processing, final
