Flowing medium presses against the paddle of the flow switch. The paddle is fitted to one end of a balance arm which is in direct contact with a pre-stressed leaf spring; at the other end of the balance arm is a permanent magnet. The magnet actuates a reed contact located within a moveable plastic housing.
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.
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.
