FineTek SF Series Paddle Type Flow Switch
The FineTek SF Series paddle flow switch offers field-adjustable paddle length to suit a wide range of flow conditions and pipe sizes, providing simple and dependable flow/no-flow indication.
How It Works
Fluid flow in the pipe deflects the paddle, compressing an internal spring and moving a magnetic element. With no flow or an empty pipe the spring is fully expanded and the magnetically activated reed switch contact stays open. As flow increases and deflects the paddle upward by roughly 20°–30° or more, the magnet moves into proximity of the reed switch and closes the contact to confirm flow.
