We have installed a ‘Water Sensor’ in the suction pipe of the pump system, in order to protect the pump from running dry. You might ask how does it work? ‘Water Sensor’ can be used to detect the water level in the suction side of the pipeline. When the two electrodes in water sensor run dry, the LORENTZ controller will automatically stop the pump and indicates Water Source Low LED. So, it will prevent your pump from getting damaged when there is not enough water in your water source to get pumped!
