Advantage Transmit information through IC card,charge accurately Install and operate easily LANtransmission data,low power,Suitable for intensive installation real-time reading control Wide area network,data transmission without distance limitation,simple installation and debugging,low sample order cost. Wide coverage,low power consumption,low cost and slower rate.
Limitations The stand-alone version of the software can only be read and controlled on a designated computer.Back up user data when replacing a pc. Greater impacts by obstacles and limited communication distance(up to 1 km).On-site debugging is a heavy workload Occasionally there will be data packet loss,high transmission rate,relatively high power consumption. At present,NB technology is not fully mature and the coverage of base stations is low.

4. If the valve cannot be closed or opened, how to find and deal with it?

If the valve is blocked by sand and gravel flowing into the pipe, the program in the water meter will try to execute the on-off valve action within 40 seconds.

If the valve cannot be switched normally, the water meter will give up the command and return the fault data to the platform.

On the platform, you can easily view the relevant information of the water meter.
