Crab Float Sensor 3mm
Description
The Sos Pump Crab Float Sensor has two sensors on the bottom that detect water. As soon as water is detected from a level of 3 mm, the sensor switches on the pump. When there is no more water, the pump switches off automatically.
Are you using the Sos Pump together with the Crab float? Then make sure that the pump is half a centimeter lower than the Crab. This way the pump can build up sufficient pressure in the hose, since the Crab starts at 3 mm and the pump works optimally from 7 mm water level.
