LoRaWAN Intelligent Water Meter with 15-25mm Diameter, 2.5-6.3 m³/h Flow Rate and Class 2 Accuracy
LoRaWAN IoT water meter features a mechanical and electrical separation design with dry structure construction. The counting mechanism is isolated from measured water, preventing interference from suspended impurities and eliminating fogging/condensation issues common in wet-type meters.
- Split structure with independent electronic unit and base meter
- Non-contact full-electronic detection with 10-liter metering accuracy
- Touch key wake-up and long-press for remote data transmission
- Infrared communication interface for parameter configuration
- Comprehensive alarm functions for battery voltage, valve status, flow anomalies, and module failures
- Scheduled data collection and auto-upload (default once daily)
- Automatic reporting mode switching during signal abnormalities
- Low power design with sleep current <10μA using 3.6V lithium battery pack
- Automatic and remote clock calibration functionality
