Bluetooth water meter
Everyone is using smart water meters and understands their advantages. However, not many people are yet familiar with Bluetooth water meters. Below, we’ll introduce you to Bluetooth smart water meters.
The Bluetooth smart water meter uses a single meter paired with multiple Bluetooth app accounts, ensuring the security of user data. Customers can use the mobile app to purchase water in real time, upload data instantly, and read their meter readings directly from their phones. The meter supports various recharge methods, including WeChat and Alipay, making it incredibly convenient for users to pay their water bills. With an IP68 waterproof rating and seamless connectivity to cloud-based service systems, the Bluetooth smart water meter perfectly meets the demands of the mobile era. It has ushered in a smart water supply service that eliminates the need for manual meter reading at homes—now, users can conveniently pay their bills entirely through mobile devices.

You don’t need to go to the water authority—just a smartphone is all you need to pay your water bill, check your user account statement, verify your balance, and handle other services such as low electricity levels.
Chengde Longzhida Intelligent Instruments & Meter Technology Co., Ltd. develops water meters that feature high quality, simple installation, and comprehensive after-sales service. For many years, we have consistently adhered to the principle of putting our customers first. If you’re interested, please feel free to contact us by phone.
