The Q-12 has several factory adjustable parameters that provide the flexibility to meet the requirements of almost any application. The Q-12 verifies fluid flow, typically in conjunction with another device. For example most of swimming pool salt chlorine generators use the Q-12 to verify sufficient flow before the generator is energized. In a spa or hot tub the Q-12 ensures sufficient flow to prevent the water heater from a meltdown. In a chiller the Q-12 prevents the system from freezing. At home the Q-12 turns on the water disinfection system when someone is getting a glass of water.\u003c\/div\u003e\n\u003c\/div\u003e\u003cp\u003e\u003cstrong\u003eAdditional Information\u003c\/strong\u003e\u003c\/p\u003e\u003cdiv class=\"product attribute additional-1\"\u003e \u003cdiv class=\"value\"\u003e0.5 Amp, 3\/4\" MPT Plumbing\u003c\/div\u003e\n\u003c\/div\u003e \u003cdiv class=\"product attribute additional-2\"\u003e\n\u003cstrong class=\"type\"\u003e\u003c\/strong\u003e \u003cdiv class=\"value\"\u003eFlow range is 0.7 - 590 GPM\u003c\/div\u003e\n\u003c\/div\u003e \u003cdiv class=\"product attribute additional-3\"\u003e\n\u003cstrong class=\"type\"\u003e\u003c\/strong\u003e \u003cdiv class=\"value\"\u003eMax. flow may be five times normal flow\u003c\/div\u003e\n\u003c\/div\u003e \u003cdiv class=\"product attribute additional-4\"\u003e\n\u003cstrong class=\"type\"\u003e\u003c\/strong\u003e \u003cdiv class=\"value\"\u003eVery low pressure drop – typically less than 1.0 psig at normal flow rate\u003c\/div\u003e\n\u003c\/div\u003e \u003cdiv class=\"product attribute additional-3\"\u003e\n\u003cstrong class=\"type\"\u003e\u003c\/strong\u003e \u003cdiv class=\"value\"\u003ePower the driving coil of small ice cube relays as well as some 30A power relays.\u003c\/div\u003e\n\u003c\/div\u003e \u003cdiv class=\"product attribute additional-6\"\u003e\n\u003cstrong class=\"type\"\u003e\u003c\/strong\u003e \u003cdiv class=\"value\"\u003eSwitches 5VDC to 240VAC\u003c\/div\u003e\n\u003c\/div\u003e \u003cdiv class=\"product attribute additional-7\"\u003e\n\u003cstrong class=\"type\"\u003e\u003c\/strong\u003e \u003cdiv class=\"value\"\u003eCan be used in ¾ inch to 6 inch pipe\u003c\/div\u003e\n\u003c\/div\u003e\u003cp\u003e\u003cstrong\u003eAlternate Part Numbers \u003c\/strong\u003e\u003c\/p\u003e","brand":"PartsForSpas.com","offers":[{"title":"Default Title","offer_id":47264209174697,"sku":"Q12DSC2\/MAY2771","price":66.14,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/7584\/4521\/files\/60357.jpg?v=1784059675","url":"https:\/\/partsforspas.com\/products\/flow-switch-q12dsc2-may2771","provider":"PartsForSpas.com","version":"1.0","type":"link"}
