| Integrated model, one user is assembled with one meter and one card, to use water only by card. After the data in the card is transmitted to the water meter, the meter opens the valve and begins water supply, after the money is used up, it will automatically cut off water supply and you must buy water again to resume water use. |

|
| Application︰ | The intelligent water meter has the function of automatic fee charging.
The users pay the fees to the water management department, which writes the volume of water into the IC card, and the users input the information of the IC card into the intelligent water meter, which can automatically begin water supply. During the period of water use, the microcomputer within the water meter will automatically check and subtract the used water volume, when the purchased water is used up, the intelligent water meter will cut off water automatically, and the user needs to buy water again.
IC card can also record the operation conditions of the meter, to control total used water volume, total purchased volume and the state of opening and closing of the valve by controlling computer or controlling software. The intelligent water meter can increase management efficiency, and effectively prevent overdue bills, avoiding the inconvenience of house call meter reading.

| Functions and Features︰ | 1. Adopted contactless IC card patent technology, which can transmit wireless data outside water meter, so it has special function of waterproof, damp-proof and anti-attack;
2. Adopted no energy consumption technology which can ensure the inside accessory battery to be used for more than 10 years;
3. Water meter, hot water meter and purified water meter all adopt unique technology of electric ball valve, which can greatly raise its performance;
4. Its inside circuit is sealed with epoxide resin; so it can work normally in the water.
