Features of pre-paid smart water meters
1. Automatic switch: recharge water for valve opening, non-value closing valve, automatic valve opening and closing. Water charges are collected in advance, and there is no need to read meters and charges.
2. Encryption security: One table and one card, automatically generate and identify the IC card password. Table cards correspond one-to-one and are not interchangeable.
3. Anti-magnetic interference: When magnetic interference occurs, the valve will automatically close, and the card will automatically open after swiping the card.
4. Early warning: When the remaining water is insufficient, the valve will be closed as a reminder to remind users to purchase water as soon as possible. At this time, swipe the card to open the valve to continue using water.
5. Low battery warning: When the battery is insufficient, the LCD display shows insufficient battery, prompting to replace the battery in time.
6. Low-power shut-off valve: If the battery is not replaced in time after the low-power warning, the valve will be closed, and the valve must be replaced before the water can be supplied.
