Bluetooth Smart Prepaid Water Meter Volumetric Measurement Type

Essentially, it is a prepaid water meter. The core logic remains "pay first, then use water". However, it is equipped with a built-in Bluetooth module, allowing users to use their smartphones to wirelessly communicate with the water meter within a short distance (usually within 10 meters) to complete operations such as recharging and querying.

• Convenient Recharge: Supports WeChat and Alipay QR code payment, no need to purchase water offline.
• Simple Installation: Wireless design, no wiring required, IP68 waterproof rating suitable for humid environments.
• Data Security: Point-to-point transmission, avoiding the risk of remote network attacks.

• Rental housing/apartments: Landlords can manage remotely to avoid disputes over unpaid fees.
• Campuses/factories: One meter, multiple cards, supporting centralized recharging and water usage statistics.
• Rural areas: When network coverage is poor, Bluetooth serves as a low-cost alternative solution.
• Renovation of old residential areas: Upgrade the existing IC card system, using Bluetooth technology to enhance user experience at a lower cost without changing the prepaid model.

In conclusion, the Bluetooth smart prepaid water meter can be regarded as a "simplified version of the Internet of Things water meter" or an "enhanced version of the IC card water meter". Although it is not the ultimate solution, at the current stage, it is a practical choice that strikes a good balance between cost, functionality and user experience.
