IC card water meter

Prepaid IC card water meter
Prepaid IC card water meter

IC card water meter is a metering tool for household charging and control. It fully realizes the prepayment charging mode and stepped water price charging mode. It needs to pay the water cost in advance to realize the stepped price charging. It directly divides the water cost into several levels and charges layers by layers, which effectively achieves the purpose of water saving, controls the specific amount of water used by people and avoids resource waste, It is a new favorite among many meter transformation projects, new rural construction, urban-rural integration, agricultural and drinking water and so on.

1. The dry-type water meter movement is made of high-strength ABS plastic. The character wheel of the movement will not be in contact with water. The display will be permanently clear and will never corrode in a humid environment.

2. Card swiping area: The user-friendly design ensures that users can accurately and effectively transmit the information in the card. The fully enclosed card slot does not affect the waterproof performance of the entire meter.

3. Appearance: Exquisite and beautiful, compact structure, small installation area, easy for users to install indoors.

4. It can support the functions of one meter, one card and multiple meters and multiple cards, which is fast, simple, reliable, and greatly improves service efficiency.

5. Water meter waterproof design is the company's patented technology. All electronic components are sealed with food-grade electronic potting glue, which has high waterproof performance, safety and reliability, and has reached the highest waterproof level IP68 standard.

6. Automatic detection function, which can be checked every 15 days to ensure reliable operation under all kinds of interference and when the meter is not used for a long time.

7. In the case of magnetic attack, battery undervoltage, and the remaining water volume is lower than the set alarm water volume, the water meter will automatically close the valve, and the Chinese characters will prompt the alarm message.

8. IC card prepayment: users pay first and then use water, which completely solves the problem of household charging.

9. Tiered water price: According to the policy, the water price is divided into different steps, and different prices are implemented within different quotas.

10. Anti-disassembly heat shrinkable film: It eliminates the effect of man-made malicious disassembly of the meter to prevent corrosion and never rust the joints, which is convenient for maintenance after use.

11. Battery: The theoretical life of the national standard ER14505M battery is 6-8 years. Our company uses the ER18505M lithium sub-waterproof battery, and the actual life is 6-8 years. The battery capacity is 1.5 times higher than the national standard. (ER14505M battery capacity is 2000mA/h---ER18505M battery capacity is 3500mA/h).

12. Static low power consumption: The quiescent power consumption current of the water meter is less than 5μA, and the national standard stipulates that it is less than 25μA, and the quiescent current is more than 5 times lower than the national standard.
