Technical performance

1. Batteries are external to facilitate maintenance and operation. 2. Fully sealed, multi-moisture-proof and waterproof treatment, fully sealed circuit part, suitable for working in immersed and waterlogged environment.

3. Using large-capacity chips to reduce the peripheral circuit has high reliability and low failure rate.

4. High-quality valves, flexible switches, strong reliability, long service life.

5. Double display, double display of wheel and LCD, higher reliability and safety.

6. High precision, high sensitivity, accuracy (error) and sensitivity (starting flow) are doubled compared with the national standard.

7. New environmentally friendly materials: the case is made of high polymer alloy material (suitable for industrial power transmission gears), with high strength (through 3MPa water pressure test), good toughness (resistance to falling and freezing), weather resistance, high temperature (resistance to boiling water), light weight, no metal corrosion, and more in line with environmental protection and sanitation requirements. Compared with other materials, it is a more ideal case material.

8. Zero Power Consumption: Static working current is zero or near zero, and battery life is long.

Intelligent Function

1. Auto-switch: recharge water for opening valves, no value for closing valves, auto-switch valves; pre-charge water, no need to enter the home meter reading, charging.

2. Encryption security: One table (one household) and one card automatically generate and identify IC card passwords, which correspond to each other and are not interchangeable.

3. Anti-magnetic interference: When disturbed by magnetic interference, the valve closes automatically and opens automatically after inserting the card.

4. Early warning: When the remaining water is 2m3 (set according to user's requirements), the valve is promptly closed, reminding users to buy water as soon as possible; at this time, the card can be switched on and the valve can continue to use water.

5. Low-power warning: when the power is insufficient, the LCD display is insufficient, prompting the timely replacement of batteries.

6. Low power shut-off valve: If the battery is not replaced in time after low power warning, the valve will be closed and the battery must be replaced before the valve can be opened for water supply.

7. LCD display: LCD display accumulative amount of water, residual water, valve switch, power status, fault code and other information.

8. Query and display: the display is usually closed, and the user can display the residual water amount and cumulative consumption by swiping the card.

9. Anti-clogging function: Control program automatically cleans the valve to keep the valve flexible.

10. Data write-back: User card can write back the data of water meter. It can read the working state of water meter in management system, which is convenient for management.

11. Management card function: inquiry card and transfer card are used by managers in inquiry and maintenance.

12. Meter Reading Function: The remote IC card water meter can respond to the meter reading instructions of the external equipment and transfer the data in the meter to the external equipment.
