Waterproof RF card water meter

The waterproof RF card water meter is a new product developed and manufactured by our company based on the original smart water meter. This meter is used to measure the flow rate of excess water in pipelines. The product complies with GB/T 778-2007 and CI/T 133-2007 standards, has a prepaid function, and can be set with multiple alarm methods to prompt users to purchase water in a timely manner. The meter measures accurately and has stable performance, making it particularly suitable for water measurement and control in residential areas, apartment users, building offices, enterprises and institutions, rural water reform and other places. This product has a good sealing level and can be fully immersed in water for use, with a protection level of IP 68 standard.

Product features:

1. IP 68 protection level, can work immersed in water.

2. Ultra low power design, with a battery life of over 6 years.

3. Adopting high-strength material movement, low starting flow rate, and high measurement accuracy.

4. No moving parts, waterproof, moisture-proof, antifreeze, sand proof, waterproof hammer, stable working performance.

5. No flow blocking components, no pressure loss or fluid blockage.

6. Adopting * ball valve, high temperature resistance>low power consumption, small pressure loss.

Product Features:

1. Prepaid function: pay first, use water later, automatically close the valve if there is no fee, and automatically connect water after paying and swiping the card again.

2. Display function: High definition LCD screen, which can intuitively view multiple data such as purchased water volume, remaining water volume, cumulative water consumption, valve status, battery status, etc.

3. Alarm function: When the remaining water level reaches or falls below the set alarm value, the water meter will automatically close the valve once, prompting the user to purchase water. At this time, the user can swipe their card to open the valve and continue using water. When the remaining water level is 0, the valve will be completely closed.

4. Rust prevention function: The water meter valve automatically opens and closes regularly to prevent the valve from rusting.

5. Anti attack function: When the water meter is subjected to strong magnetic or electrical attacks, the water meter will automatically close the valve and record the information of the attack. The valve can only be opened after external interference is eliminated.

6. Anti theft water function: If the controller can still receive the counting signal sent by the sending water meter after the smart water meter valve is closed, the remaining water volume displayed by the controller will become negative and the valve will automatically close for 1 second.
