Well, just take 5 minutes to read the blog and follow the simple 3 rules, all your doubts will be gone!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Rule No.1: The application scenario determines the type of water flow sensor to use.<\/h2>\n\n\n\n<p>Though you can find a dozen or more water flow sensors on our web market, typically they can be divided into two types:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Large diameter copper pipe<\/li><li>Small diameter plastic pipe<\/li><\/ul>\n\n\n\n<p>YF-B1 ~ YF-B7 belongs to the Large-diameter type. The <a href=\"https:\/\/www.seeedstudio.com\/catalogsearch\/result\/?q=YF-B\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"YF-Bx serials (opens in a new tab)\">YF-Bx serials<\/a> are commonly used in industry, agriculture, and animal husbandry, and therefore require the use of copper pipes that are more resistant to pressure and better resistant to corrosion.<\/p>\n\n\n\n<p>While small-diameter ones are usually used for household appliances. The most common of these are the YF-S201 and YF-S402. The YF-S201 is suitable for card dispensers, water vending machines, while the YF-S402 is suitable for smaller diameter household appliances such as water dispensers, coffee makers. By the way, both YF-S402 and YF-S201 are commonly used in Arduino and Raspberry Pi water flow sensor projects.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1030\" height=\"473\" src=\"https:\/\/blog.seeedstudio.com\/wp-content\/uploads\/2020\/05\/water-flow-sensor-work-LIST-1030x473.jpg\" alt=\"\" class=\"wp-image-33196\" srcset=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2020\/05\/water-flow-sensor-work-LIST-1030x473.jpg 1030w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2020\/05\/water-flow-sensor-work-LIST-300x138.jpg 300w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2020\/05\/water-flow-sensor-work-LIST-768x353.jpg 768w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2020\/05\/water-flow-sensor-work-LIST-1024x470.jpg 1024w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2020\/05\/water-flow-sensor-work-LIST.jpg 1134w\" sizes=\"(max-width: 1030px) 100vw, 1030px\" \/><\/figure>\n\n\n\n<p>Sometimes, you need to measure both water flow and water temperature, like water heaters, or dishwashers. Then you need to choose a water flow sensor with a temperature sensor.

The water flow sensors on our website are all in the British Standard Pipe(BSP). That&#8217;s why can find G1\/2 or G3\/4 in the sensor name.<\/p>\n\n\n\n<p>Don&#8217;t worry if you are using the  American National Pipe Thread(NPT). You can still use the BSP water flow sensor with your NPT pipe, Just need to do some simple conversions.
