Function
1 Touchless type IC card, completely sealed foragainst water.
2 Dual-key encryption,one card with onecode.
3 One card for different meter or one card forone meter.
4 Valve will shut down for warning when theremaning water is less than the warning line,and the valve willopen when swipe the card on the induction aera. (Warning ofinsufficient water volume)
5 LCD will show low power when the remaningpower is less than the warning line,and the user should change thebattery duly. (Warning of power shortage)
6 Data-read-back routes function,Managementcenter can collect the data from the user card which includingwater consumption,battery status and the report of the humandisturbance etc.
7 Small starting flow and high precision.
8 LCD ,Show the volume of newpurchasing,surplus and totally accumulative water. (Warningof insufficient water volume)
