These switches monitor liquid, gas or air flow. They are used to protect pumps, motors, and other equipment against low or no flow, to stop liquid cooled engines when flow is interrupted, and to shut down burners when air flow through heating coils fail. Find a wide selection of switches to fit your application.
Operation is simple and dependable with no mechanical linkage as the flow switch is magnetically actuated. The lower body holds the flow vane and one magnet, which controls the switch actuating magnet in the separate upper housing. In most applications the switch is normally off with the pipeline flow forcing the vane against the vane spring.
Tested being installed in thousands of pipelines and processing plants around the world. A magnetically actuated switching design gives superior performance. There are no bellows, springs, or seals to fail. Instead, a free-swinging vane attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm.
Used to monitor unattended equipment and protect it from costly damage. Utilizes a rugged, hermetically sealed reed switch which is encapsulated in a polypropylene switch housing that fits into a standard heavy duty leak proof brass body or optional 303 Stainless Steel body.
