The decentralized water metering and wireless remote transmission solution, with wireless remote-transmission water meters as the core, employs wireless communication technologies such as NB-IoT, LoRa, 4G, and GPRS to upload meter data to the platform, realizing remote management and real-time monitoring of water usage. The water meters use high-precision mechanical base meters to collect flow data and offer multiple electromechanical conversion methods including photoelectric direct reading, non-magnetic pulse, and magnetic resistance sensing, meeting data acquisition requirements in different application scenarios. This solution resolves the problems of high cost, low efficiency, long cycles, and low accuracy associated with manual meter reading, while further strengthening protection of user safety and privacy.
