It installs in the flow cell and gives the controller a positive signal that water is actually moving through the sample line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy the interlock matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA chemical controller should only feed when there is flow to carry and dilute what it doses. If the pump is off and the controller keeps feeding, concentrated chemical pools in the line, which is hard on plumbing and equipment and does nothing for the water. The flow switch is the piece that makes feeding conditional on circulation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat you get\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis listing is the switch on its own. The flow cell that houses it is a separate item, so this suits an existing installation where the cell is sound and the switch has failed.\u003c\/p\u003e","brand":"IPS Controllers","offers":[{"title":"Default Title","offer_id":48628733083860,"sku":"ISI-451-1004","price":59.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_0339174f-5615-4508-adee-238fa0815749.png?v=1788749337","url":"https:\/\/www.activepoolsupply.com\/products\/ips-controllers-flow-switch-only-flsw","provider":"Active Pool Supply","version":"1.0","type":"link"}
