This critical component is engineered to accurately detect liquid flow, ensuring that equipment only operates when necessary to prevent dry firing or circulation failures. By integrating this 1-inch flow switch into your plumbing infrastructure, you ensure seamless automation and protection for your pumps, boilers, and heat exchangers.\u003c\/p\u003e\u003cp\u003eThe FS5-1 functions by utilizing a paddle mechanism that reacts to the kinetic energy of the fluid within the pipe. When flow is detected, the paddle deflects, mechanically actuating a snap-action switch that completes or breaks an electrical circuit to your system controls. This durable, time-tested design provides immediate feedback, allowing for responsive system monitoring and enhanced operational longevity.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Built to withstand rigorous industrial and commercial piping environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecise Detection:\u003c\/strong\u003e Engineered for sensitive and repeatable flow actuation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliable Integration:\u003c\/strong\u003e Provides seamless compatibility with standard 1-inch plumbing connections.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Primarily utilized in commercial hydronic boilers, chiller systems, liquid transfer processes, and high-capacity water heating loops to provide essential flow proofing for automated equipment cycles.\u003c\/p\u003e","brand":"McDonnell \u0026 Miller","offers":[{"title":"Default Title","offer_id":43123966771294,"sku":"114780","price":428.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/114780_image_ca59d27d-72b5-42cd-bcd8-9ad22fc715a5.png?v=1786027311","url":"https:\/\/nationalboilersupply.com\/products\/mcdonnell-miller-114780-fs5-1-1-flow-switch","provider":"National Boiler Supply","version":"1.0","type":"link"}
