Automated system for monitoring and maintenance of fluid level in swimming pools and other contained bodies of water
First Claim
1. An automated system for monitoring and maintaining fluid level in an environment containing fluid, comprising:
- a sensor assembly comprising a proximity sensor and a transmitter, said proximity sensor comprising one or more conductors encapsulated in a substantially non-conductive material having a thickness up to 7 mm thick, wherein the conductors are disposed in a lower section of the sensor assembly, said lower section having a generally flat profile and a cross sectional thickness between 2 mm and 10 mm;
a remote controller, said remote controller is operatively connected to at least one fluid control valve and in communication with the sensor assembly;
a substantially watertight housing, said housing having a wall that encloses the sensor assembly in a manner such that the one or more conductors does not directly contact the fluid, wherein the housing wall adjacent to the proximity sensor is between 1 mm to 3 mm;
wherein the sensor assembly senses fluid level changes in the environment by measuring an amount of time required for the conductors to charge to a preset voltage, wherein the sensor assembly transmits a signal to the remote controller when a measured fluid level deviates from a predetermined target value, wherein the remote controller turns the fluid valve on or off in response to the signal.

Abstract
An automated system for monitoring and maintaining fluid level in a swimming pool, spa, or other environment containing water is provided. The system includes a sensor assembly having a microprocessor and a proximity sensor encapsulated in a non-conductive material. A lower section of the sensor assembly has a flat profile and at least a portion of the proximity sensor is positioned in the lower section. The sensor assembly transmits a signal to a remote controller when the water level measured is above or below a predetermined target value. The remote controller in turn causes a remote water valve to turn on or off. In certain implementations, the sensor assembly incorporates a precision mounting system and algorithm, which work together to provide the end user with a means to mount the sensor easily and maintain precise operational level of the water. The combination of the physical mounting system and the range and resolution of the proximity sensor allow for precise maintenance of water level at the preferred level.
