Chapter III: Working Flow Chart
The device ensures the water level to be maintained between MID and LOW through three
sensors and an intelligent algorithm of SPT (single pumping time).
The working flow chart as follow:
▪
When the water level is lower than LOW level, the LOW light will turn off and the water
pump will start the 1st pumping for a SPT period.
▪
If the water level reaches the MID or HIG level, the pump will stop pumping water.
▪
If the 1st SPT period pumping is completed and the water level has not reached the LOW
level, the device will check the LOW light or start the 2nd pumping.
▪
If the water level fails to reach the LOW level after two pumping, the alarm will be triggered.
