Main functions

1. Prepaid function

The products adopt prepaid gas measure form. The users can only use the gas after paying for it. When the user's card is inserted in the table with a gas, the gas meter shows the purchasing volume and open valve words.

When the gas supplying, the Countdown intelligent module. The buzzer rings once when the residual volume equals to the alarming volume. Then it can remind the users. At the same time, the characters displays on the screen to show the absence and alarm once after each reduced by 1 cubic meters.

3. Gas cutting down function when the gas volume is zero.

4. Security feature: It is only available for the single user with the card.

5. Anti Interference Function

6. Intuitive reading of the data.

7. With pulse output interface realizing the centralized Meter Reading
