Vertical prepaid water meter model: DN32---DN300

Main functions:

1. Display function

By pressing the "Display" button or inserting the "User Card", the "Remaining" and "Overdraft" water usage information can be displayed, and the "Purchase Water" information can be displayed when recharging the table. Simultaneously display status information such as "open valve", "close valve", and "insert/remove card".

2. Water purchase and recharge function

After inserting the user card that has been recharged with purchased water, the control box will add the amount of water purchased in the card to the original remaining water amount and create a new remaining water amount.

3. Water input restriction function

The RF card cold water meter has a storage limit set. When the sum of the purchased water in the user's card and the remaining water in the meter exceeds the set storage limit, the user's card recharge operation is not accepted.

4. Query function

Users can check the water volume information by pressing the "Display" button on the control box or inserting the "User Card".

5. Valve closing and payment function

Vertical prepaid water meters can set alarm and overdraft limits. When the remaining water in the table reaches the alarm level, the valve automatically closes to remind the user that there is not much remaining water in the table. At this point, insert the user card into the table and open the valve.

New usage features:

1. The circuit is designed to be fully waterproof, ensuring that it can adapt to the usage environment of large meters.

2. The protective cover is a cold plate shell, ensuring that the circuit is not bumped during use.

3. The on/off valve indicates that the switch status can be directly read using a mechanical pointer, reducing on-site switch misjudgment.

4. Emergency valve opening function ensures that users can achieve emergency valve opening water supply under abnormal water conditions.

5. Anti backflow function: During normal use, if the front end of the meter stops or runs water, the water behind the meter will be blocked by the water meter's reverse valve, and the water will not flow back to serve as a check.

6. The on-site maintenance, electronic control, and mechanical parts are designed in a single garden for easy maintenance and repair.
