What design features of prepaid water meters are there to extend their service life and improve their practicality?

Prepaid water meters are made of brass that meets drinking water standards. This material is not only corrosion-resistant, but also ensures the safety of water quality, avoiding water meter damage or water quality pollution caused by material problems, thereby extending the service life of the water meter.
Due to the easy operation of the contactless card method, the meter has a fully sealed design and good waterproof performance. This can effectively prevent moisture from entering the water meter, avoid circuit failures or rust of mechanical parts caused by humid environments, and improve the durability and practicality of the water meter.
Prepaid water meters have a data security preservation function, and data can be saved for 10 years even after power failure. This means that the user's water use data and payment records will not be lost due to power failure, providing reliable data support for users and water supply companies.
The water meter is designed with the function of opening/closing the valve regularly, which is to prevent the valve from rusting. Through regular activities, the flexibility of the valve can be maintained, and valve failures caused by rust can be reduced, thereby extending the service life of the water meter.
Prepaid water meters are designed with low power consumption and the battery can be used for 6 years. This reduces the inconvenience and cost of battery replacement, and also reduces the risk of water meter damage due to battery leakage and other reasons. When the prepaid water meter is subjected to strong magnetic effects, the valve will automatically close. This design can prevent water meter failure or water waste caused by malicious damage or accidental strong magnetic interference, and improve the safety and practicality of the water meter.
Prepaid water meters usually also have real-time monitoring and intelligent management functions. These functions enable water supply companies to efficiently control water use, detect and deal with abnormal water use behavior in a timely manner, thereby reducing management costs and water waste. At the same time, for users, they can also better understand their own water use and establish water-saving awareness.
