A flow switch is an industrial device used to detect and monitor the flow of liquids or gases within a pipeline system. It activates or deactivates an electrical signal when the flow reaches a preset level, ensuring proper system operation and protection.

Widely used in HVAC systems, water treatment plants, pumping stations, fire protection systems, and industrial automation, flow switches help prevent equipment damage by detecting low or no-flow conditions. They are available in various types such as paddle flow switches, thermal flow switches, and electronic flow switches.

Known for their reliability, quick response, and easy installation, flow switches are essential safety and control components in modern industrial and commercial flow systems.
