Introduction
Automated controllers, flow meters, and flow switches play a crucial role in monitoring chlorine, pH, and water flow. Regular calibration and maintenance ensure accurate readings and reliable dosing.

What Does This Involve?

• Annual calibration: A certified technician verifies sensor accuracy and corrects any offsets.
• Frequent manual testing: Even with an automatic controller, daily manual tests (DPD1/DPD3) are essential to confirm the controller’s accuracy.
• Flow switch checks: The flow switch shuts off chemical dosing if water circulation stops. If it malfunctions, excessive chemicals might be added, posing safety risks.
