Customer metering refers to the process of measuring and recording the amount of a product or service used by a customer. This is typically done through the use of specialized devices, such as meters or gauges, which track the consumption of resources such as electricity, water, or gas. The data collected through customer metering is used for billing purposes, as well as for monitoring and managing resource usage. It allows companies to accurately charge customers for the amount of resources they have used, promoting fair and transparent pricing. Additionally, customer metering can also help customers become more aware of their resource consumption and make more informed decisions about their usage habits.
