Description

A Water Flow Switch is a monitoring device used to detect the movement of water within a pipeline and trigger a signal or alarm when flow occurs. It is most commonly used in fire protection systems to indicate the activation of sprinklers or water discharge during a fire event. The switch plays a critical role in system monitoring, safety, and compliance with fire safety standards.

When water starts flowing, the internal paddle or sensor of the flow switch is activated, sending an electrical signal to a control panel, alarm system, or monitoring device. Water Flow Switches are designed for reliability, quick response, and long service life. Manufactured using high-quality materials such as Brass, Stainless Steel, and durable plastics, they are suitable for various pipe sizes and operating conditions.
