Main technical indicators:

Work pressure: maximum working pressure of 1.6MPa, pressure loss ≤ 0.063MPa;

※ Battery and operating voltage: 3.0V lithium battery;

※ Battery working time: service life>6 years;

Data storage: The data is self memorized and retained for at least 10 years;

※ Usage conditions: Cold water meter medium temperature: 0 ℃~40 ℃, relative humidity<93%; Hot water meter medium temperature: 0 ℃~70 ℃, relative humidity<93%;

Main functional features:

※ Ladder water pricing function: It can achieve four different billing levels, advocating water conservation;

※ Paid function: Users can purchase water before use, and if they owe the fee, the valve will be closed to stop the water supply.

At the end of each month, the water usage for the current month is automatically saved, and information for 6 consecutive settlement months can be saved and queried;

Users can swipe their card to check the cumulative water usage, remaining water usage, and cumulative water usage for this month and the previous month;

※ One card function: One card can control the electricity meter and water meter.

※ Display synchronization function: The LCD display and mechanical part display are synchronized, even if there is a circuit fault and the LCD screen cannot display, it can still refer to the mechanical display.

※ Alarm function: Battery undervoltage, insufficient available water, strong magnetic interference, and other fault information will prompt an alarm on the LCD screen.

※ Data upload function: Every time a user purchases water, relevant information will be brought back to the management system, allowing the management to understand the user's water usage situation and the status of the meter.

※ Valve self maintenance function: The valve rotates at regular intervals to promptly remove valve scale and ensure valve flexibility.

※ Blacklist query: Users who do not come to buy water for a long time can be included in the blacklist to supervise their water usage.

※ Convenient battery replacement: The bottom of the water meter has a specially designed cover for battery replacement, making battery replacement particularly convenient. Batch battery replacement is no longer a problem for water management departments.

※ Moisture proof function: The product adopts overall sealing and waterproof technology in the process, so it can work in humid environments or short-term water immersion situations.
