Gas Metering

A smart gas meter not only measures gas flow but use wireless communication to connect to local or wide area networks allowing infrastructure maintenance, remote location monitoring and automatic billing. It also has leakage and shock detection systems that can greatly increase safety by detecting emergency situations and enabling the immediate and remote cutting of the gas flow in case of seismic activity or gas leakage.

Smart gas meters are powered by batteries, and thus low-power devices play a crucial role in defining system configurations.

ST supports designers with our unique system-level application know-how and a compelling portfolio of semiconductor products, evaluation boards and software development kits to overcome the design challenges posed by smart gas meter applications.

Our ultra-low-power sub-GHz RF communication solutions support all major protocols: long-range – including WM-BUS and proprietary LPWAN protocols such as LoRa and Sigfox – and short-range such as dual NFC/RFID interface tags and ultra-low-power Bluetooth Low Energy (BLE) and 802.15.4 system-on-chips. Together with ultra-low-power STM8L or STM32L microcontrollers, our solutions help applications meet the battery lifetime expectancy needed in smart gas meters.
