The Model IFS-WP is a flow switch used in liquid flow lines carrying water or any fluid not harmful to brass, stainless steel, or EPDM 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 operating control. 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.
