SFX Paddle Type Level Switch

Thermal dispersion flow switches measure the velocity of a liquid inside a pipe or channel. The switch’s probe contains two key components – a heating sensor and temperature sensor. The heating sensor is positioned closest to the flowing liquid and provides a consistent heat. The temperature sensor measures the temperature emitted from the heating sensor. When liquid is flowing, there is a temperature difference between the two sensors. The temperature difference has a proportional to the flow velocity (fast flowing liquids will result in greater heat differences and vice versa). Since the device contains no moving parts, has no wear and tear and maintains a long lifespan.

SF Series is a paddle flow switch for use with a wide variety of fluids. The paddle flow switch uses the force of the liquid flow to actuate a reed switch. It can be activated by as little as 5gpm (19.4l/m) flow.

The SF series is a paddle flow switch product line with field adjustable paddle length for a variety of flow conditions and pipe sizes. The SF paddle flow switch utilizes the force of the fluid flow in a pipe to move the paddle. As the fluid flow moves the paddle an internal spring is compressed, which moves a magnetic element. With no flow, or with an empty pipe condition, the paddle flow switch spring is fully expanded and the magnetically activated reed switch contact is open, indicating that a no-flow or empty pipe condition exists. As flow increases, the spring is compressed and the magnetic element moves toward the reed switch. When the flow moves the paddle in an upward angle of at least approximately 20⁰~30⁰ (or more) the magnet moves into proximity of the reed switch and activates it and the contact closes to indicate that a fluid flow condition exists.
