LoRaWAN wireless digital prepaid brass magnet stop valve control meter magnet water meter
Description:
The lorawan prepaid Water Meter is a smart water meter based on the LoRaWAN standard communication protocol.It adopts LoRa wireless technology communication, which has the characteristics of long communication distance and convenient networking.It is convenient for remote meter reading and controlling, effectively reducing operator's door-to-door meter reading and improving meter reading efficiency.
The water meter adopts electron and mechanical separation structure design, which is free from magnetic interference and ensures accurate measurement. The base meter and the wireless acquisition module can be completely separated and run independently, which is convenient for installation and maintenance.
Features:
Fully electromechanical separation, easy for maintenance; Mechanical and electrical running separately without interference. easy for maintenance; Far more than RF cards,user-friendly,wireless network planning,handset reading.
Function introduction
No. | Function name | Function brief introduction | Function parameter |
1 | measurement | Using multiple signal sources combination to calculate technic and software anti-interference technology, can check the true and false of the signal |
|
2 | meter number management | The only identify number of each meter, can only be modified by specialized machine | 14 decimal numbers: 000000000000-999999999999 |
3 | Meter base number management | If the water meter has a mechanical counter, the electronic readings and mechanical readings should be consistent. | 0000.0000 cube-9999.9999 cube |
4 | Correction time | Correct anytime without leap year | 2000 year~2100 year, Minimum correction to seconds |
5 | Reading on assigned day | Save measurement data for a specified day |
|
6 | Failure testing | Alarm when strong magnetic interference or short-circuited on sampling line |
|
7 | Battery voltage detection | Alarm when the battery voltage reaches the lower limit | The lower limit is based on voltage value, generally lower 0.2~0.4V than battery voltage |
