Accurate flow detection is essential for salt chlorine generator performance, and this Hayward flow sensor helps the system confirm that water is moving properly before chlorine production begins. When a flow sensor fails or reads inconsistently, the generator may stop producing chlorine, display flow-related warnings, or operate less reliably.This replacement sensor is intended for compatible Hayward chlorine generation systems and is used to restore communication between water movement and sanitizer output. It is a smart repair part for pools experiencing flow alerts after routine filter cleaning, pump service, or cell inspection have ruled out other causes. For technicians and pool owners maintaining salt systems, replacing a worn sensor can help protect the equipment while keeping water care more consistent. Replacement flow sensor for compatible Hayward salt systems Helps verify water movement before chlorine generation Useful when troubleshooting flow warnings or shutdowns Supports proper equipment protection and sanitizer control Designed for dependable integration with Hayward components
