They are high performance devices and can integrate up to 8 speed chords and take into account 4 water height measurements. Versatile, the multi channel version can carry out 8 measurement points on 8 different outfalls with 1 single device and can integrate up to 10 Input\/Output modules (analogue, digital, etc.). In addition, these devices have a graphic display and boast advanced functions (maths functions generator, multi-variable data logger, height\/speed law degraded mode, possibility of integrating an external chord).<\/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\">Standard mounted inputs\/outputs<\/div><div class=\"text\"><div class=\"text-container\"><p>\n3 to 6 mandatory\u00a0base modules:<\/p>\n<ul>\n<li>1 isolated active analogue output: current 4-20mA, 0-20mA, 0-24mA,<\/li>\n<li>2 static relay digital outputs (50V &#8211; 10mA) usable on frequency outputs,<\/li>\n<li>2 isolated current inputs 4-20mA, 0-20mA, 0-24mA.<\/li>\n<\/ul>\n<p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">Optional inputs\/outputs<\/div><div class=\"text\"><div class=\"text-container\"><p>\nJusqu\u2019\u00e0 7 modules \u00e0 choisir parmi :<\/p>\n<ul>\n<li>1 isolated active analogue output: current 4-20mA, 0-20mA, 0-24mA,<\/li>\n<li>2 static relay outputs usable as frequency outputs ( up to 1kHz),<\/li>\n<li>2 isolated,passive current inputs 4-20mA, 0-20mA, 0-24mA,<\/li>\n<li>2 isolated, passive analogue 0-10V inputs: 0 to 15V voltage,<\/li>\n<li>2 PT100\/PT1000 temperature inputs \u2013 taking up the physical space of 2 modules,<\/li>\n<li>2 contact 5V 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<\/div><div class=\"text\"><div class=\"text-container\"><p>\n8 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>Single channel<\/li>\n<li>Multi-channel<\/li>\n<li>River<\/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>:\u00a0Measuring flow rate at purification plant intakes\/outputs, measuring flow rate in combined or separate sewer systems, etc.<\/li>\n<li><strong>Raw water<\/strong>:\u00a0Measuring flow rate in irrigation channels, measuring flow rate in rivers up to 500 m wide, measuring flow rate in rainwater harvesting networks, 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_831co_en_bd.pdf\">Uf 831 CO\/RV<\/a>\u00a0datasheet<\/span>.<\/em><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Uf 831 CO and Uf 831 RV flow meters have been designed for flow measurement of free surface flows.
