How can smart water meters effectively conserve water resources?
China has long suffered from water shortages, with per capita water consumption even lower on average. We are classified as a country facing severe water scarcity. Moreover, China is actually the world’s largest consumer of water. Faced with such a dire situation, it has become urgently necessary to find effective ways to conserve water.
Smart water meters can help conserve water effectively. In addition to recording and electronically displaying water usage, smart water meters can also control water consumption according to prearranged settings—setting them apart from conventional mechanical water meters.

1. Water consumption can be recorded and displayed electronically.
2. Water consumption can be controlled according to the agreed-upon terms, and the water bill calculation for tiered pricing can be completed automatically. Additionally, it supports water data storage functionality.
3. Data transmission and transaction settlement are conducted via IC cards, offering convenient transactions and accurate calculations.
The water meter developed by our company, It can record the operational status of meters and, via a microcomputer and under system management software, display the meter’s operating conditions in real time, enabling effective monitoring. This helps address the unfavorable situation of overdue water bills and on-site meter readings, thereby saving manpower, material resources, and financial costs for property management or water supply departments and improving management efficiency. Feel free to call for more information.
