Method and apparatus for automatically maintaining a predetermined desired level of water in a swimming pool, and the like

摘要

An improved method and apparatus for automatically monitoring the level of water in a swimming pool, or the like, by monitoring the level of a float within a float chamber supported by water siphoned from the pool system, for detecting when the level of water has fallen a predetermined amount or distance below a predetermined desired level and for controlling the input of fresh water into the pool system in response to the detected level for restoring the water in the pool to the predetermined desired level as determined by the position of the float on the siphoned water within the float chamber being restored to a float position indicative of said predetermined desired level of water in the pool.
