What Are Flow Switches?

Flow switches detect the movement of liquids or gases in a system. They trigger alerts or shut down equipment when flow is too low or stops, protecting your system from damage.

Paddle Flow Switches

Paddle flow switches use a simple paddle mechanism to sense fluid flow. Their reliable design makes them popular for monitoring flow in industrial and HVAC applications.

Flow Switches in HVAC Systems

Flow switches are vital in HVAC systems, ensuring fluids and air flow properly. They help prevent overheating and system failures by shutting down equipment if flow drops.

Air Flow Switches for HVAC

Air flow switch HVAC models specifically monitor airflow, detecting blockages or airflow issues early to maintain system efficiency and safety.

Why Use Flow Switches?

Flow switches enhance safety, reduce costly repairs, and prevent downtime. They provide real-time flow monitoring so you can catch problems before they escalate.

Installation and Maintenance

Installing flow switches is straightforward. Routine maintenance ensures accurate performance and extends their lifespan, keeping your systems running smoothly.

Frequently Asked Questions

Paddle flow switches use a mechanical paddle to detect flow and trigger a switch, making them ideal for water applications. Inline flow switches monitor flow within the pipe itself, while electronic flow switches use sensors for precise, non-mechanical detection, suitable for both water and air systems.

Replace a flow switch if it fails to trigger, shows signs of corrosion or mechanical wear, or if the electronic sensor malfunctions. Regular inspection helps prevent system downtime.

Yes, flow switches designed for HVAC systems help monitor water or air flow, protecting pumps, fans, and heating/cooling coils. Ensure the switch is rated for the specific system type and flow range.

Some switches are specific to water or air, while others are versatile. Always verify the switch’s material compatibility and flow rating to avoid damage or inaccurate operation.

Key factors include fluid type, pipe size, flow rate, pressure rating, and whether a manual reset or automatic response is needed. For HVAC applications, consider temperature range and compatibility with existing controls.

Yes. Many electronic flow switches provide signal outputs compatible with building automation or monitoring systems, allowing remote alerts and integration with HVAC or water management controls.
