GENERAL DESCRIPTION
The FPS flow switch operates according to the proven paddle bellows principle. The flowing media acts upon the paddle, actuating a micro switch. The switching point may be freely adjusted and the device mated to different nominal pipe sizes by means of both the replaceable paddle and the easily accessible range screw located within the housing. 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 to accommodate lower switching values than standard. Although horizontal flow orientation is preferred, the devices may be installed in any orientation with some additional variation to the switching ranges indicated in the order details section seen below.
