product description
This product adopts advanced non-contact RF card technology and SMT process to manage users' water and electricity meters simultaneously. It has the advantages of accurate measurement, high accuracy, security and confidentiality, reliable performance, rich functions, low power consumption, and simple operation. It is particularly suitable for water and electricity measurement and control in residential areas, apartment users, building offices, enterprises and institutions, and other places.

Function and characteristic
1. LCD (Liquid Crystal Display) displays clear and intuitive content.
2. During normal operation, the LCD screen displays information such as remaining power, meter number, and cumulative electricity consumption in a cyclic manner.
3. Power outage alarm function: When the remaining power reaches the alarm value (which can be set), the meter will automatically power off to remind users to purchase electricity in a timely manner. After swiping the card, users can continue to use electricity until the remaining power reaches zero and the meter will power off again.
4. Load control function: When the electrical load exceeds the set value, the meter will automatically cut off power. After the load decreases, the meter will automatically resume power supply within about 5 minutes.
5. Adopting high-power magnetic holding relays, with a wide range and strong overload capacity, long-term overload operation will not cause damage.
6. One card function: The electricity meter and water meter can share one RF card and one management system. One user card can control two electricity meters and three water meters simultaneously.
