This water meter uses magnetic-free counting technology to read water usage. Based on metal detection principles, the sensor detects a rotor with metal film and converts it into a pulse measurement signal, providing accurate metering without interference from external strong magnets.
1.Magnetic-free Induction Using magnetic-free induction principle for metering, the water meter has strong anti-interference ability and can intelligently judge the direction of water flow, achieving bidirectional metering. 2.Data Storage With hourly, daily, monthly, and other periodic data and dense data recording functions, sensor signal strength, and data can be saved for a long time even after a power outage. 3.Intelligent Monitoring The water meter can issue alarms for low battery, sensor faults, magnetic interference, etc. It also allows setting alarms for overdrawn water usage and low remaining balance. 4.Remote Valve Control The water meter can remotely monitor valve malfunctions and report valve action data to the cloud platform. When fees are overdue, the water valve can be automatically closed. Valve switching can be periodically set to prevent rust and blockages. 5.Payment Modes The water meter has an embedded five-level water price system, supporting various payment methods such as platform prepaid, meter-end prepaid, and mixed payment. 6.Ultra-Low Power Consumption Designed for low power consumption and built with a large-capacity battery, the water meter has a battery life of more than 6 years. 7.Technical Support The water meter can be protocol docking and interface docking to meet different platform requirements. 8.OTA Remote Upgrade All devices can be remotely upgraded online without the need for replacement, disassembly, or proximity to the meter. 9.Convenient Payment Supports mobile payments such as WeChat public accounts, Alipay, and mini-programs. Customers can also query usage, balance, and payment information.
