The decentralized water metering and smart card meter solution uses a water meter equipped with a pulse-emitting device as the base flow meter, employs an RF card as the information carrier, and integrates a controller and electrically controlled valve to form a water metering instrument with prepayment and settlement functionality. This solution is suitable for low-density metering scenarios. It resolves the issues of high cost, low efficiency, long cycles, and low accuracy associated with manual meter reading, while achieving effective management of water consumption and tariffs.
