Clean Water Level Sensor – Agma 22


Mac3 Agma22 is a compact float switch alternative, designed to be fitted vertically to a submersible pump. When used for pump control, Agma22 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.

Agma22 is designed to be used with clean water or water with very low solid content. Not suitable for slurry or foul water applications (use the AgmaW instead). Avoid using in water containing iron or other ferrous materials as these may affect operation.
