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 |
8 | Remote diagnosis | Meter reading,battery voltage,specified day reading,Failures,Valve Status,balance,Magnetic interference status | remote diagnosis available whenever necessary |
