Versatile, the dual channel version can carry out 2 measurement points on 2 different outfalls with 1 single device and can integrate up to 3 Input\/Output modules (analogue, digital, etc.).<\/p>\n<div class=\"block\"><div class=\"title\">Nature of equipment<\/div><div class=\"text\"><div class=\"text-container\"><p>\nFixed flow meter<\/p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">Width of channel<\/div><div class=\"text\"><div class=\"text-container\"><p>\nUp to 30m (in clean water)<\/p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">Standard mounted inputs\/outputs<\/div><div class=\"text\"><div class=\"text-container\"><p>\n2 isolated, passive current inputs 4-20mA, 0-20mA, 0-24mA<\/p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">Optional inputs\/outputs<\/div><div class=\"text\"><div class=\"text-container\"><p>\nUp to 3 modules\u00a0to choose from:<\/p>\n<ul>\n<li>1 isolated, active analogue output: current 4-20mA, 0-20mA, 0-24mA,<\/li>\n<li>2 static relay output s usable as frequency outputs (up t o 1kHz),<\/li>\n<li>2 isolated, passive current inputs 4-20mA, 0-20mA, 0-24mA,<\/li>\n<li>2\u00a0isolated, passive analogue 0-10V inputs: 0 to 15V voltage ,<\/li>\n<li>2\u00a0PT100\/PT1000 temperature inputs &#8211; taking up the physical space of 2 modules,<\/li>\n<li>2 contact 5 V inputs (pulse or state).<\/li>\n<\/ul>\n<p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">Protection<\/div><div class=\"text\"><div class=\"text-container\"><p>\nIP 67<\/p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">Accuracy<\/div><div class=\"text\"><div class=\"text-container\"><p>\nUp to 0,5 %<\/p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">Troubleshooting help<\/div><div class=\"text\"><div class=\"text-container\"><\/p>\n<ul>\n<li>Oscilloscope function (echo displayed)<\/li>\n<li>Gain<\/li>\n<li>Quality index<\/li>\n<\/ul>\n<p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">Maximum number of speed chord<\/div><div class=\"text\"><div class=\"text-container\"><p>\n2 chords<\/p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">Available models<\/div><div class=\"text\"><div class=\"text-container\"><\/p>\n<ul>\n<li>Standard<\/li>\n<li>Dual channel<\/li>\n<li>Dual chord<\/li>\n<\/ul>\n<p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">Typical applications<\/div><div class=\"text\"><div class=\"text-container\"><\/p>\n<ul>\n<li><strong>Waste water<\/strong>:\u00a0Flow measurement\u00a0at treatment works\u00a0inlets\/outfalls\u00a0(small channels).<\/li>\n<li><strong>Raw water<\/strong>:\u00a0Flow measurement\u00a0in irrigation channels, small rivers, etc.<\/li>\n<\/ul>\n<p>\n<\/div><\/div><\/div>\n<p><span style=\"color: #000000;\"><em><span style=\"color: #000000;\"><br \/>\nDownload <a style=\"color: #000000;\" href=\"https:\/\/www.ultraflux.net\/wp-content\/uploads\/2014\/05\/uf_811_co_en_bd.pdf\">Uf 811 CO<\/a>\u00a0datasheet<\/span>.<\/em><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Uf 811 CO flow meter has been designed to measure free surface flows (open channels, small rivers or partially filled pipes).
