Work to protect and regulate the groundwater system was carried out with the aim of limiting high water levels in the Seine and protecting Paris and its suburbs from the risk of flooding.<\/p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">DESCRIPTION OF THE APPLICATION<\/div><div class=\"text\"><div class=\"text-container\"><p>\nThe application that interests us is situated in the region of Troyes on a feeder canal, called the Baires canal. Its level fluctuates in order to regulate the Seine. The measurement point is situated on the canal, just below a bridge, and consists of a flow rate measurement for managing high water levels. The distance between the banks is around 7.6m.<\/p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">EQUIPMENT USED<\/div><div class=\"text\"><div class=\"text-container\"><\/p>\n<table>\n<tbody>\n<tr>\n<td colspan=\"2\">FLOW METER<\/td>\n<\/tr>\n<tr>\n<td>Uf 831 CO dual-chord converter<\/td>\n<td>SM 1684 wetted probes<\/td>\n<\/tr>\n<tr>\n<td><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-1479\" src=\"https:\/\/www.ultraflux.net\/wp-content\/uploads\/2014\/06\/Uf-831-220x190.jpg\" alt=\"Convertisseur Uf 831\" width=\"220\" height=\"190\" \/><\/td>\n<td><img decoding=\"async\" loading=\"lazy\" class=\"alignnone  wp-image-1480\" src=\"https:\/\/www.ultraflux.net\/wp-content\/uploads\/2014\/06\/SM-1684-210x259.jpg\" alt=\"Sonde mouill\u00e9e SM 1684\" width=\"160\" height=\"197\" \/><\/td>\n<\/tr>\n<tr>\n<td>This converter can be used to take reliable and precise measurements of any type of free surface flow.<\/td>\n<td>Two pairs of probes are used to improve precision via two measurement chords.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">RESULTS<\/div><div class=\"text\"><div class=\"text-container\"><p>\nAssuming we have the available straight lengths and knowledge of the installation, the measurement uncertainty can be around 2 % for this type of application.<\/p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">ADVANTAGES<\/div><div class=\"text\"><div class=\"text-container\"><\/p>\n<ul>\n<li>Continuous measurements,<\/li>\n<li>Dynamic measurements,<\/li>\n<li>Repeatability,<\/li>\n<li>Quick installation.<\/li>\n<\/ul>\n<p>\n<\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":3,"featured_media":0,"parent":5737,"menu_order":4,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v21.1 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Flow rate measurement of a canal | Ultraflux - flow meters<\/title>\n<meta name=\"description\" content=\"Use of ultrasonic flow meter and probes for channel flow measurement: a reliable &amp; accurate solution.
