By measuring water surface velocity, blockages and backflow inside of a pipe can be detected. It will be useful to use the data for cleaning blockages before a pipe being clogged, because it will be more cost-effective than fixing a pipe after it is fully damaged.<\/p>\n\n\n\n<p>This proof of concept can be implemented using the Evaluation kit featuring A121 sensor, a lens and the Exploration tool. In this video, the A121 sensor is placed 35cm from the water surface at the angle of 45 degrees.<\/p>\n\n\n\n<p><strong>UPDATE!<\/strong> The surface velocity implementation is now also available as a use case example in our SDK.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Surface velocity measurement using Acconeer A121\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/AYpbGlhXUQs?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Moreover, it can also be used outside for measuring water surface velocity such as rivers and streams.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/acconeer.com\/wp-content\/uploads\/2023\/03\/surface_velocity_measurement.jpg\" alt=\"\" class=\"wp-image-4529\" srcset=\"\/wp-content\/uploads\/2023\/03\/surface_velocity_measurement.jpg 768w, \/wp-content\/uploads\/2023\/03\/surface_velocity_measurement-384x512.jpg 384w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Hardware<\/h2>\n\n\n\n<p>One XE121 Evaluation Board, one XC120 Connector Board and one LH120 lens are necessary for this implementation.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\r\n \t<li>XE121 Evaluation Board can be purchased <a href=\"https:\/\/www.digikey.se\/en\/products\/detail\/acconeer-ab\/XE121\/16582348\" target=\"_blank\" rel=\"noopener\">from Digi-Key<\/a><\/li>\r\n \t<li>XC120 Connector Board can be purchased <a href=\"https:\/\/www.digikey.se\/en\/products\/detail\/acconeer-ab\/XC120\/16582340\" target=\"_blank\" rel=\"noopener\">from Digi-Key<\/a><\/li>\r\n \t<li>LH120 lens can be purchased <a href=\"https:\/\/www.digikey.se\/en\/products\/detail\/acconeer-ab\/LH120\/16582338\" target=\"_blank\" rel=\"noopener\">from Digi-Key<\/a><\/li>\r\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Software<\/h2>\n\n\n\n<p>Flash the Evaluation kit through the Exploration tool.
