The electronic level controller with 2 sensors will automate aquarium water top off. Since safety is our number one concern, we include two float switch sensors with our electronic water level controller. The first float switch sensor triggers the feed pump (sold separately) to maintain the desire water level. The second float switch sensor ensures dependability and offers overflow protection. Our water level controller can also be used to protect pump from running dry. It can be utilized in three ways :
1.In this mode the power supply will turn on if the water level in the sump is low AND there is enough water in the storage tank. The power supply will turn off if the water level in the sump is high AND there is not enough water in the storage tank.

With this set up the power supply will turn on as soon as the water level in the sump drops below the set level. The power supply will turn off if the water level in the sump is high the set level.

2. The power supply will turn on when the level falls below the minimal level of float sensor1 and will turn off when water rises the set point of the flow sensor1. The float sensor2 acts as a backup sensor in the event the float sensor1 is stuck. The level controller will not allow the power supply to turn on if the water level in the sump reaches the maximum level of float sensor2.

3. Immerse the sensor1 and sensor2 in the measured solution(sump).With this set up the power supply will turn on when both sensors detected that the water level is below the minimum level and stop only when the water rises the maximum level of both sensor.
