Metering is the process of measuring the quantity of a resource, such as electricity, water, or gas, consumed by a user. This is typically done using a device called a meter, which records usage over time. Accurate metering is essential for billing purposes and helps in monitoring consumption patterns. In addition to billing, metering plays a crucial role in resource management and conservation. By analyzing data from smart meters, for example, utility companies can identify trends and encourage users to reduce waste. This not only helps in managing resources more efficiently but also supports sustainability efforts.
