Automatic pool and spa water leveler on a non-static line

摘要

A water level detection system in a pool, spa, fountain or water feature forming a body of water within, the water level detection system is provided with a tap line coupled to a plumbing line on a suction or supply side of a filtration system and admitting water from the pool, spa, fountain or water feature such that the change in level of the water in the tap line corresponds to a change in level of the water in the pool, spa, fountain or water feature. A sensing module is mounted to the tap line and has at least one sensor for detecting the height of a column of water or the pressure of a column of air in the water tap line. A controller is coupled to the sensing module and adapted to collect the data from the sensors that detect changes in the level of the water level of the body of water, communicate the detection of such a change, and report such a change to initiate addition or removal of water from the body of water to adjust the water level in the body of water to a set point.

1. A water level detection system in a pool, spa, fountain or water feature forming a body of water within, said body of water being at a specified water level, the water level detection system comprising:
a tap line coupled to a plumbing line on a suction or supply side of a filtration system and admitting water from the pool, spa, fountain or water feature such that the change in level of the water in the tap line corresponds to a change in level of the water in the pool, spa, fountain or water feature; a sensing module, the sensing module mounted to the tap line and having at least one sensor detecting the height of a column of water or the pressure of a column of air in the tap line; and a controller coupled to the sensing module such that the controller is adapted to collect the data from the at least one sensor that detects changes in the level of the height of the column of water or the pressure of the column of air in the tap line and thereby changes in the water level of the body of water, communicate the detection of such a change, and report such a change to initiate addition or removal of water from the body of water to adjust the water level in the body of water to a set point water level.
