Prices of Yanqing household water meters // Quotation Sales: Manager Gao Phone 1500-1377-453 Online QQ: 2817513962 When enterprises develop and produce products, they must prioritize credibility and not produce non-compliant products. Even if it means earning a little less profit, they should choose materials that meet national standards! Function Features
◇ Utilizes a closed non-contact IC card, moisture-proof, dust-proof, and anti-attack.
◇ One meter per household, one card per meter, designed to ensure user safety, non-dissemination, and
non-repeatability during use, eliminating the possibility of counterfeit card production through various means.
◇ Anti-strong magnetic interference function: When the water meter encounters external strong magnetic field interference, the water meter valve automatically closes. Before the magnetic interference is eliminated, the valve cannot be opened. Once the magnetic interference is removed, the user card can be used to open the valve.
◇ Alarm function: When the remaining water amount of the water meter equals the set alarm value, the valve closes to stop water supply and alarms, reminding users to quickly purchase water. Users can communicate with the IC card water meter using the payment card to open the valve.
When the remaining water amount is 0
m3, the valve
closes, and can only be opened for water supply after proper communication with a valid payment card and the water meter.
◇ Low battery voltage valve closure function: When the battery power is insufficient, the valve automatically closes and saves water usage information. The valve cannot be opened, and can only be opened after replacing the battery with a payment card and stop meter card.
◇ Data write-back function: Each time the user purchases water, the management terminal will extract usage data from the IC card.
◇ Lost card reissue function: If the user loses the card, they can go to the management terminal to handle the corresponding reissue procedures. After reissuing the card in this system, the original user card becomes invalid.
Uses Chinese character LCD display, with intuitive display content.
◇ Purchase amount inquiry function: When the user uses the payment card to communicate with this meter, the display can show the last water purchase amount, cumulative usage, and available remaining amount for user inquiry.
Valve and battery automatic protection function: This company's IC card water meter automatically opens and closes the valve once a month to prevent the valve from rusting and being unable to operate. It also prevents lithium batteries from working long-term under low current conditions, avoiding battery passivation.
Dual display function: LCD and base meter counter double display measurement. If the LCD is damaged, the mechanical counter will be used as the standard.
