LoRaWAN Smart Water Meter 15-25mm with 2.5-7.8 m³/h Flow Range and Wireless IoT Connectivity
LoRaWAN IoT smart water meter integrates mechanical water meter base, electric ball valve, magnetoresistive sensor, MCU, wireless communication module, and control circuitry. Features mechanical-electrical separation design with high-capacity lithium battery for long-term power supply. Utilizes LoRaWAN wireless communication with spread spectrum technology to automatically upload user water data to gateway (default once daily).
Dry structure design isolates counting mechanism from measured water, preventing interference from suspended impurities and eliminating fogging/condensation issues common in wet-type meters.
- Accurate measurement with non-contact electronic detection (10-liter metering accuracy)
- Key wake-up function with long-press for remote data transmission
- Infrared communication interface for parameter reading and configuration
- Comprehensive alarm system for battery voltage, valve status, flow anomalies, and module failures
- Scheduled data collection and upload (default once daily) with platform command execution
- Automatic reporting mode switching between daily and monthly based on signal conditions
