Smart meters and advanced metering infrastructure have attracted much attention and provide practical benefits such as the ability to visualize energy consumption and reduction of carbon dioxide emissions. The smart gas metering system has been developed, and is composed of three main components: a WAN device (Pu-NCU); ad-hoc mesh networks (U-Bus Air); and ultrasonic smart gas meters with the new communication port (U-Bus). This paper describes the smart ultrasonic gas meter, which employs the "Repetitive Inverse Transit Time Difference Method."
