What type of system is a chemical feeder considered to be?

A chemical feeder is classified as an automated dispensing system primarily because it is designed to introduce precise amounts of chemicals into the pool water automatically. This system helps maintain water chemistry at optimal levels without the need for manual intervention, ensuring consistency and efficiency in chemical dosing. Automated feeders can be programmed to dispense chemicals based on either time intervals or water quality readings, which enhances the safety and performance of the pool environment.

In contrast to other options, a manual dispensing system would require regular human action to add chemicals, while a monitoring system primarily focuses on testing and reporting the water quality without active chemical introduction. A filtration system is designed to remove impurities and particles from the water but does not play a role in the introduction of chemicals.
