A utility meter is a device used to measure the consumption of utilities such as electricity, water, or gas in homes and businesses. These meters provide essential data that helps utility companies bill customers accurately based on their usage. Typically installed outside buildings, utility meters can be analog or digital. Analog meters have dials that require manual reading, while digital meters display usage on a screen. Some modern meters, known as smart meters, can transmit data wirelessly, allowing for real-time monitoring and more efficient energy management.
