Smart IC card water meter/RF card water meter

Smart IC card water meter/RF card water meter is used to measure and control the total volume of water flowing through the tap water pipeline. This table has the characteristics of high reliability, high accuracy, and low power consumption. All parameters comply with the requirements of international standards (GB/T778.1-3-2007) and urban construction industry standards (CJ/T133-2012).

Functional Features

1. Using an IC card without any exposed electrodes, it has good moisture resistance and is easy to use.

2. The user card is encrypted with dual keys, one card and one password.

3. It has anti electromagnetic interference function.

4. It has the function of one card, one meter, or one card, multiple meters.

5. When there is insufficient remaining water, prompt the user to purchase water in a timely manner.

6. When the battery voltage is too low, prompt the user to replace the battery.

7. It has a data retrieval function. When a user purchases water from the management center with a card, the accumulated water consumption, battery status, interference frequency, etc. in the water meter corresponding to the card can be retrieved back to the management center.

8. Low initial flow rate and high accuracy.

9. Display function: Parameters such as the current water purchase amount, remaining water amount, and cumulative water consumption can be effectively displayed on the LCD screen. Users can view the remaining water amount and cumulative water consumption information in the table through their user card.
