Whale® Automatic Bilge Field Switch - BLA 131691

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.B. As with all submersible electrics, attention is needed during installation to ensure that wiring connections remain above water level. Specified output is US gph open flow.
