Introduction:

Radio frequency card prepaid water meter, abbreviated as IC card smart water meter, is an instrument used to measure the total volume of water flowing through the tap water pipeline. Corrosive liquids cannot be used. This product is divided into cold water meter and hot water meter. It has a compact structure, high sensitivity, accurate measurement, and is suitable for water supply charging and management.

2. Work pressure: 1MPa.

3. Pressure loss:< 0.1MPa.

4. Measurement level: B level.

5. Common flow rates: 1.5 cubic meters per hour, 2.5 cubic meters per hour, 3.5 cubic meters per hour.

6. Overload flow rate: 3 cubic meters per hour, 5 cubic meters per hour, 7 cubic meters per hour.

7. Maximum reading: 99999.9 cubic meters.

8. Water temperature: 0-40 ℃ (cold water gauge), 0-90 ℃ (hot water gauge).

9. Applicable water quality: clean tap water and hot water without impurities.

10. Battery life:>6 years.

RF card prepaid water meter function introduction:

(1) Convenient battery replacement: The bottom of the water meter has a specially designed cover for battery replacement, making battery replacement particularly convenient;

(2) Anti theft writing function: Each IC card has a corresponding number, a password of 32 bits, and up to 232 combinations, which are not easy to crack. At the same time, it adopts a two-way verification mechanism, where the reader and writer verify the legitimacy of the IC card, and the IC card verifies the legitimacy of the reader and writer;

(3) Waterproof function: The product adopts an overall sealed waterproof process in the process, with a protection level of IP68, so it can work in humid environments or short-term water immersion situations;

(4) Insufficient balance alarm function: When there are 2 tons of water remaining in the user's table (this value can be set according to the user's needs), the valve will be automatically closed to prompt the user to purchase water. At this time, the user can use the card to open the valve to continue using water, and use this time to purchase water from the management department, without delaying the user's normal water use and facilitating residents' daily life;

(5) Low power consumption: Adopting a new type of low-power, high output torque non pressure loss motor control valve, effectively reducing the power consumption of the water meter and increasing the service life of the battery;

(6) The water meter card swiping sensing area is equipped with a card slot: effectively preventing card swiping instability caused by long distance, incorrect position, etc., making card swiping stable, reliable, and convenient;

(7) Water theft warning function: When water theft is detected, the valve will automatically close and must be handled by the management department before water can be reused.
