Fuction:

1.There are two data reporting methods.Magnetic trigger to report data:The magnet triggers the hall components of the meter module,and the trigger time must be greater than 2S.

Timed and active reporting:the reporting time slice is automatically allocated according to the Device Eui of the meter module,and the data is reported every 24 hours.

2.It will detect voltages of various states of metering module in real-time and report.

3.Support dual reed switch,dual hall metering mode.

4.Support power-down storage function,there is no need to re-initialize the measurement value after power-off.

5.Support magnetic attack detection,it willgenerate alarm sign when malicious magnetic attack is detected.

6.It can save 10 years of annual frozen data and monthly frozen data of the last 128months,and the cloud platform can query historical data.

7.Support wireless near and remote parameter settings.The remote parameter setting is realized through the cloud platform,and the near parameter setting is realized through the production test tool.

8.Valve type can be set to support remote valve control and valve fault detection(which is optional).

9.When the power is down,the valve will be closed and reported.
