The KOBOLD model FPS flow switch operates according to the proven paddle bellows principle. The flowing media acts on the paddle thus actuating a microswitch. The switching point can be freely adjusted and the device mated to different nominal pipe sizes by means of the replaceable paddle in conjunction with the additional adjustment features. The electrical switching cavity is separated hermetically from the process fluid by means of a bellows. The FPS-6000P version of the flow switch has been specially designed for minimum switching values. See table for switching values. The devices can be installed in any orientation.
