LoRa Spread Spectrum Smart Gas Meter
Description
A smart gas meter is equipped with an intelligent controller based on LoRa spread spectrum communication technology installed on the base meter to realize remote meter reading, alarm, valve control and other functions.
Key Strengths
- Timed reporting and push-button trigger reporting
- Long reading distance and strong anti-interference ability using LoRa spread spectrum technology
- Step pricing, real-time price adjustment and amount settlement
- Remote recharging and monitoring
- Free Network adopting ISM public frequency channel
- Data analysis and storage
- Valve shut-off due to non-metering
- Error-correcting mechanism with high meter reading accuracy
Safety Features
- Remote valve control
- Valve shut-off due to overflow
- Valve shut off due to no gas used for a long time
- Valve shut off due to loss of communication
- Reporting due to failure
- Abnormally flow rate alarm
- Valve shut off due to zero gas consumption
