Patent ID: 8828728

Claim:
A method of monitoring errors in an aquatic environment monitoring system, the method comprising: measuring one or more error values in the environment monitoring system using the environment monitoring system, said measuring one or more error values including: rotating a disc-shaped chemical indicator apparatus of the environment monitoring system in a clockwise direction and taking one or more clockwise readings from the chemical indicator apparatus with an optical reader of the environment monitoring system; rotating the disc-shaped chemical indicator apparatus in a counter-clockwise direction and taking one or more counter-clockwise readings from the chemical indicator apparatus with the optical reader; correlating the one or more clockwise readings with the one or more counter-clockwise readings to generate a friction error value; determining at least one confidence level based on the one or more error values; determining if the confidence level exceeds a threshold value stored in associated with the environment monitoring system; and generating a correction instruction using a dosing calculator associated with the environment monitoring system, the correction instruction for correcting a condition associated with the one or more error values.
