Whale Automatic Bilge Field Switch

The electric field sensor senses the water level in bilges or grey waste tanks and automatically controls the operation of a 12 or 24 volt bilge pump. The switch automatically turns the pump on when it senses a water level of 51mm and turns off when the water level returns to below 13mm. Designed for pleasure boat applications and not suitable for flammable liquids, diesel and chemicals.\n\n[table id=531 /]\n\nN.B.
