Kelco Engineering F Series Paddle Flow Switch are tough, but highly sensitive paddle flow switch suitable for a wide range of flow control applications in both hot and cold liquids and a variety of chemicals.
The Descriptions of Kelco F Paddle Switch
The electrical housing of the switch is a separate assembly and locks onto the wet end of the switch. It can be easily and safely removed for servicing, without disturbing electrical wiring. This unique feature and the inclusion of a built-in manual override make the F Series a very versatile flow switch.
The ‘F-H’ models are the standard models in the F Series. The ‘F-RL’ models are the low voltage options specifically designed for use in Ex hazardous applications and with low wetting currents.

Paddle Trimming Calculator
The paddles for our F Series switches are supplied at a set length. These paddles can be cut down to suit your pipework and flow rate. We recommend using our Paddle Trimming Calculator (linked above) to find the correct paddle length for your application.
