Waste Water Level Sensor – Agma W


Mac3 AgmaW is a compact float switch alternative, designed to be fitted vertically to a submersible pump. When used for pump control, AgmaW activates a connected pump when the water levels are high enough for pump use, and deactivates the pump when the water level has decreased to the set minimum.

AgmaW is designed to be used with clean water, sewage, flood water and water containing solids and debris. Avoid using in water containing iron or other ferrous materials as these may affect operation.
