TCOIFS01BF-1,

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 operatingcontrol. Where an operating control failure
would result in personal injury and/or loss of property, 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.
