There is a simple rotating wheel with a magnet and when the liquid flows the wheel is rotated and a hall effect sensor measures how many times he wheel is rotated and accordingly gives pulses. By counting the number of pulses you can easily calculate the flow rate as well as the amount of liquid dispensed\u003c\/p\u003e","brand":"Indian Hobby Center","offers":[{"title":"Default Title","offer_id":42475547820075,"sku":"1828","price":499.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/6796\/1387\/products\/9-1.png?v=1762683272","url":"https:\/\/www.indianhobbycenter.com\/products\/yf-b1-1-2-inch-brass-water-flow-sensor-sen-hz21wi44mm","provider":"Indian Hobby Center","version":"1.0","type":"link"}
