The DDZY2397 Single Phase Smart Water Metering System is an advanced IoT energy meter designed for efficient water management and conservation. This intelligent electricity meter features comprehensive energy measurement, power parameter monitoring, time-sharing measurement, real-time freezing, on-off control, and dual communication interfaces including LoRaWAN and RS485.

• Forward and reverse active energy measurement with separate accumulation
• 12-month historical electricity consumption storage and display
• Real-time voltage, current, power, power factor, and frequency monitoring
• Overload protection and remote disconnection/transmission capabilities
• Programmable rate periods with two sets of tariffs (sharp, peak, flat, valley)
• Multiple freezing functions: instantaneous, regular, daily, agreed, and hour freezing
• Event recording for zero clearing, programming, proofreading, power down, and relay operations
• Active data upload via LoRaWAN wireless network (default 4-hour interval, configurable)
• Automatic calibration upon power-up and network connection

The meter features a comprehensive LCD display showing current consumption, historical data, rate status, and operational indicators. Status LED lights provide visual feedback for active power measurement and LoRaWAN module connectivity.

Direct access wiring configuration with dedicated terminals for reactive pulse output, active pulse output, multifunctional clock output, and RS485 communication.
