Flow Switch

🔧 Product Overview

A Flow Switch is a device used in fire protection systems to detect the flow of water in the piping network. When water begins to move due to sprinkler activation or manual valve opening, the flow switch sends a signal to the fire alarm control panel. It is a critical component for early fire detection and system monitoring.
