Name: | Quantity | Description | Function | |
Super clean card | 1 | Clean all information in the meter. | ||
The meters can be used for new demo after cleaning the information. | ||||
Super | 1 | Each time the card is inserted into the meter, 1000 liters will be added into meter. | Add water quantity into the meter. | |
user card | When the quantity is add into the meter, the valve in the meter will be open. When the quantity is used up, the valve will be closed automatically. | |||
This card is for demo, the value in it will not empty after read by meters and can be added in to meter again after the meter is cleaned. | ||||
Mark | As this meter is used for domestic, the value in user card will be transferred into meter, and the card is empty and the card should be debited again to use water in actual use. | |||
