The IC card water meter is a metering tool for household charging and control. It fully realizes the prepaid charging mode and the tiered charging mode. It needs to pay the water cost in advance to realize the tiered charging. It directly divides the water cost into several levels and charges at different levels. It effectively achieves the purpose of water saving, controls the specific amount of water used by people, and avoids resource waste. It is a large number of water meter transformation projects, new rural construction Urban rural integration, agricultural drinking water and other new favorites in the work of using meters.

Product features
| The dry type water meter movement made of high-strength ABS plastic is used. The movement does not contact with water. The word wheel displays permanently and clearly, and it will never corrode in a humid environment. |
| Card swiping area: humanized design ensures that users can accurately and effectively transfer the information in the card, and the card slot is completely closed without affecting the waterproof performance of the whole meter. |
| Appearance: exquisite and beautiful, compact structure, small installation area, convenient for indoor installation. |
| It can support the functions of one meter, one card and multiple meters and multiple cards, which is fast, simple, reliable and greatly improves the service efficiency. |
| Automatic detection function, once every 15 days, to ensure that the meter can work reliably in the case of various interferences and long time without use. |
| When the magnetic attack, battery undervoltage, and residual water volume are lower than the set alarm water volume, the water meter will automatically close the valve, and Chinese characters will prompt the alarm information。 |
| Ladder water price: according to the policy, the water price is divided into different ladders, and different prices are implemented in different quota ranges. |
| Static low power consumption: the static power consumption current of the water meter is lower than 5 μ A. National Standard Provisions 25 μ A below, the static current is more than 5 times lower than the national standard. |
| Battery: National standard ER14505M battery has a theoretical life of 6-8 years. Our company uses ER18505M lithium sub waterproof battery, and the actual service life is 6-8 years. The battery capacity is 1.5 times higher than the national standard |
