General Description
FPS flow switches are used
wherever reliable control for min. or max.
liquid flow is required. The flow switch
operates on the paddle-bellows principle.
The flowing medium exerts a force on the
paddle and thereby actuates a micro
switch. The interchangeable paddle, in
conjunction with an adjustment screw,
allows for a wide variety of switching
points and adaptation of the instrument to
different pipe sizes.
The internals of the instrument are
separated from the process by the
bellows, making the FPS an excellent
choice for dirty media. The FPS-6000 is a
special design used with extremely low
switching points.
