Operating Principle

The float follows the liquid level as it changes, causing the attached float magnet to move into the field of the valve magnet causing the valve to change position. Depending on how the Pneumofloat is manufacture the valve can be normally closed,  giving an output as liquid levels rise, or normally open, giving an output as liquid levels fall.
