The centralized water metering solution uses wired remote-transmission water meters combined with battery-powered (or mains-powered) concentrators, providing a stable and efficient comprehensive remote meter-reading solution for high-density centralized metering scenarios. The water meters adopt high-precision mechanical base meters to collect flow data and support multiple electromechanical conversion methods such as photoelectric direct reading and non-magnetic pulse, meeting data acquisition requirements in various application scenarios. Depending on the number of connected water meters, a battery-powered concentrator (supporting 30+ ) or mains-powered concentrator (supporting 800+) can be selected to upload the data from all connected meters to the enterprise water management platform.
