TIMEWAVE LoRaWAN Digital Water Meter 15-25mm with <10μA Power & 864-865MHz Communication
Advanced IoT smart energy meter designed for efficient water resource management with long-range wireless communication and ultra-low power consumption.
The LXSY-TW LoRaWAN smart water meter features an electromechanical separation design comprising dry water meter base meter, electric ball valve, magnetic resistance sensor, MCU, lithium battery pack, LoRaWAN wireless communication module, and control circuit. Engineered for long communication distance, large capacity, fast installation, and extended service life.
- Split structure with electronic units independent from base table
- Accurate measurement with non-contact electronic detection and 10-liter precision
- Touch button wake-up function with long-press for immediate online data transmission
- Infrared communication interface for parameter reading and configuration
- Comprehensive alarm functions for abnormal states, measurement faults, battery voltage, and valve status
- LoRaWAN timing upload with configurable intervals (default once daily)
- Ultra-low power design with 3.6V lithium battery pack and dormant current <10μA
- Automatic and remote clock calibration functionality
