Automated chemical controller
Definition
An electronic controller that continuously measures pH and free chlorine in a recirculated splash pad and doses chemicals automatically to keep readings in range.
Automated chemical controllers (Pentair IntelliChem, Hayward Sense and Dispense, Stranco LMI) are standard on new municipal recirculated splash pads. They sample water every few seconds and meter acid, chlorine and CYA as needed, replacing manual hourly logging with continuous control.
Controllers don't replace daily inspection — operators still walk the pad, check probes, and verify with hand tests — but they catch chemistry drift far earlier than the old hourly-log model.
