A gas meter is a device used to measure the amount of gas consumed by a household or business. It tracks the volume of gas flowing through the pipes, allowing utility companies to bill customers accurately based on their usage. Gas meters can be mechanical or digital, with digital meters often providing more precise readings and additional features like remote monitoring. These meters are typically installed outside buildings and are connected to the gas supply line. Regular maintenance and readings are essential to ensure safety and efficiency. Understanding how to read a gas meter can help consumers monitor their gas usage and manage their energy costs effectively.
