The Agma W level regulator is a very useful instrument when used directly on pumps which must work in very small wells, for which the common float switch would not have enough room to work. The switching mechanism is inherited by Agma 22 and is magnetic.
This device is usable even in the presence of debris in the water and, if it is not possible to use a floating tilting, can also be used in the presence of waste water in compliance with a periodical verification and cleaning of the mechanisms of buoyancy.
