An intelligent water meter is a new type of water meter that utilizes modern microelectronics technology, modern sensor technology, and intelligent IC card technology to measure water usage and transmit water usage data for settlement transactions. Compared to traditional water meters, which generally only have the function of collecting flow rate and displaying water usage with mechanical pointers, it represents a significant advancement.

Smart water meters, in addition to recording and displaying water usage, can also control water usage as agreed and automatically calculate the tiered water pricing fees, while also offering water usage data storage capabilities.
