The HELI SWT flow monitor from Helios is a mechanical device designed to monitor the flow velocity in ducts and pipes. It is particularly important when using electric heating registers to ensure that the flow velocity remains within specified parameters. The flow monitor features a robust design equipped with a stainless steel paddle that allows for reliable measurement. Installation is done on the outside of ducts, ensuring easy setup. The switch can be configured as either a normally open or normally closed contact, providing flexibility in application. The HELI SWT flow monitor responds to both under- and over-speed conditions, with minimum values set at approximately 1.5 m/s for under-speed and 3.0 m/s for over-speed. These features make it an essential component in many industrial applications.

• Mechanical monitoring of flow velocity in ducts and pipes
• Stainless steel paddle for high stability and durability
• Flexible switching as normally open or normally closed
