GENERAL
The Model IFS is a flow switch used in liquid
flow lines carrying water or any fluid not harmful
to brass, stainless steel, EPDM or fluorosilicone,
and not classified as a hazardous fluid.
This switch can serve as a way to start and stop
electrically operated equipment when a flow or no
flow condition occurs in a variety of applications.
This device is designed for use only as an operat-
ing control. Where an operating control failure
would result in personal injury and/or loss of prop-
erty, it is the responsibility of the installer to add
devices (safety, limit controls) that protect against,
or systems (alarm, supervisory systems) that warn
of control failure.
