FPS Paddle Bellows Flow Monitor

Brand: KOBOLD Instruments, Inc.

The KOBOLD flow monitor FPS operates according to the proven paddle bellows principle. The flowing medium acts on the paddle thus actuating a microswitch.

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 device section is separated hermetically from the process fluid by means of a bellows. The special version of the flow monitor has been specially designed for minimum switching values. See table for switching values. The devices can be installed in any position.
