A method for determining a concentration of a chemical of interest in a recirculating analyte system includes the steps of selecting a first indicator threshold, measuring the flow rate of the recirculating analyte system, controllably adding a known amount of reagent to the recirculating analyte system at an known flow rate, repetitively measuring an indicator of the recirculating analyte system downstream from the addition of the reagent, and computing the concentration of the chemical of interest of the recirculating analyte system when the indicator measurement crosses the indicator threshold.

Automated titration in a recirculating fluid system

A method for determining the total alkalinity (TA) in a recirculating water system without adversely impacting the pH of the water includes the steps of selecting a pH threshold (Th), measuring the flow rate of the moving body of water (f), controllably adding a known amount of acid to the recirculating water system at an acid flow rate (f), repetitively measuring the pH of the recirculating water system downstream from the addition of the acid, and computing the total alkalinity of the recirculating water system when the pH measurement falls below the pH threshold.

Measuring total alkalinity in a recirculating fluid system

A system for controlling water within an aquatic facility includes a water chemistry controller, a variable rate water pump adapted to move water in the facility, and a variable rate motor driver operationally coupled to the water pump for variably energizing the water pump. The variable rate motor driver is coupled to the water chemistry controller to allow the water chemistry controller to manage the operation of the water pump.
