Kl-233 Level Controller With 2 Sensor - 150x85x42mm, 2w Ac 220v | Digital Display, Triple Operation Modes, Dual Sensor Protection

The electronic level controller with 2 sensors automates aquarium water top-off, prioritizing safety. It includes two float switch sensors: one triggers the feed pump to maintain the desired water level, while the second provides overflow protection. Additionally, it can protect the pump from running dry. It offers three operation modes:

Mode A-1:
The power supply turns on if the water level in the sump is low and there is enough water in the storage tank. It turns off if the sump water level is high and there is insufficient water in the storage tank.
Mode A-2:
The power supply turns on when the sump water level drops below the set level and turns off when it reaches the set level.
Mode B:
The power supply turns on when the water level falls below the minimal level of float sensor 1 and turns off when it rises to the set point of float sensor 1. Float sensor 2 acts as a backup.
Mode C:
Immerses both sensors in the measured solution (sump). The power supply turns on when both sensors detect that the water level is below the minimum level and stops only when the water rises to the maximum level of both sensors.
