The prepaid cold water meter is an intelligent water meter based on a rotary vane water meter, integrating a reed switch signal acquisition device, a low-power electrically controlled valve, a microcomputer control system, and a smart card information system. This product transforms the traditional water billing method from "use first, pay later" to "pay first, use later." Each water sale transaction is accurately recorded, addressing the challenges of "difficult fee collection and messy accounts" in water management. Prepaid water meters with remote meter reading capabilities can also provide real-time water usage statistics, offering accurate data for water billing settlements.

Features

* Measurement: Uses a high-strength material movement mechanism with low starting flow and high measurement accuracy.

* Prepaid function: Pay first, use later; automatically shuts off when credit is exhausted and resumes water flow after recharging via card.

* Water sale record archiving: Each water sale operation is accurately recorded, ensuring clear and unalterable accounts, with multiple statistical reports for easy querying.

* One-card function: If the same user installs two or more water meters or simultaneously uses our company’s water, electricity, and gas meters, multiple smart meters can be managed with a single card for convenience.

* Display function: High-definition LCD screen allows intuitive viewing of purchased water volume, remaining water volume, cumulative water usage, valve status, battery status, and other data.

* Alarm function: When the remaining water volume reaches or falls below the set alarm value, the meter automatically shuts off once to prompt the user to purchase water. The user can still open the valve by swiping the card to continue using water. The valve shuts off when the remaining volume is zero.

* Anti-rust function: The water meter valve automatically opens and closes periodically to prevent rusting.

* Anti-tamper function: When the meter is subjected to strong magnetic attacks, it automatically shuts off and records the tampering incident. The valve can only be reopened after the external interference is removed.

* Low-power design: The entire control circuit is designed for low power consumption with minimal static current, ensuring a battery life of over 6 years.

* Waterproof design: Key components undergo multiple waterproof treatments, providing excellent waterproof performance.

* Tiered water pricing function: Offers options for both single water price and tiered water price programs.
