What are K factors for flow switches and how do I use them?
A. K Factors are used in adjusting paddle lengths. If the flow rate in the pipe exceeds the maximum adjustment on the flow switch, a change can be made in the paddle length. Modifying the paddle length is a simple procedure that will adapt the flow switch to a broader range of applications.
