Its single-pole double-throw switch contact (SPDT) can make One circuit is turned on, while cutting off another circuit. The water flow switch is usually used in places that require interlocking or 'cut-off' protection. The number of blades and the length of the blades can be adjusted to meet the needs of different pipe diameters and flow rates.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eModel: HFS-15(1\/2') HFS-20(3\/4') HFS-25(1')\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eMaximum pressure: 16kg f\/cm2(1600Kpa)\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eInsulation resistance: Over 100M, DC500VM\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eWithstand voltage: AC 1500V\/1minute\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eContact life: 1000K times\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eBellows life: 500K times\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eFluid temperature: -20?ĕ?150??(under the condition of non-icing fluid)\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eWeight: 0.7Kg\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e1 x Flow Switch\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e1 x Set Paddles\u003c\/span\u003e\u003c\/div\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/3C\/5E\/2485fb3d-5f97-4a35-b152-a59766952a7b.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/74\/4B\/d0ca6e9c-1850-41c8-b966-3574562ca1dc.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/C6\/63\/334d6d18-0c06-4f0c-bc63-1d495d8f661a.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/5E\/77\/0901a0f2-9e76-4241-bc1d-0be83ebb9ce6.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/4E\/C7\/ad40472b-3451-4fe0-bd9f-9f090675fe95.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/80\/68\/cf652735-aa62-4009-93e5-4a7682a09eb0.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e","brand":"Electronic Pro","offers":[{"title":"HFS-15","offer_id":40704619610307,"sku":"1883004","price":1126.59,"currency_code":"ZAR","in_stock":true},{"title":"HFS-20","offer_id":40704619643075,"sku":"1883004","price":1126.59,"currency_code":"ZAR","in_stock":true},{"title":"HFS-25","offer_id":40704619675843,"sku":"1883004","price":1126.59,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2787\/9162\/products\/2485fb3d-5f97-4a35-b152-a59766952a7b.jpg?v=1631869986","url":"https:\/\/electronic-pro-south-africa.myshopify.com\/products\/hfs-20-15-25-liquid-water-oil-sensor-control-automatic-paddle-flow-switch","provider":"Electronic Pro ","version":"1.0","type":"link"}
