Equipped with a multi-variable data-logger and maths functions generator, it can also receive optional input\/out modules (analogue, digital, temperature, etc.). The Uf 821 takes into account the different flow regimes by Reynolds number calculation.<\/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>\n2 static relay outputs (50 V &#8211; 10 mA) usable as frequency outputs (up to 1KHz)<\/p>\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>\nUp to 4 modules to 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 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 &#8211; 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 style=\"font-weight: 400;\">Oscilloscope function (echo displayed)<\/li>\n<li style=\"font-weight: 400;\">Gain<\/li>\n<li style=\"font-weight: 400;\">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>\n4 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 pipe<\/li>\n<li>Multi-pipe<\/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\"><ul>\n<li><strong>Drinking\/raw water<\/strong>:\u00a0Measuring flow rate and metering, supervising networks, etc.<\/li>\n<li><strong>Waste water<\/strong>:\u00a0Measuring flow rate in pumping stations, at purification plant intakes\/outputs, in networks, etc.<\/li>\n<li><strong>Environmental engineering<\/strong>: Energy balance report.<\/li>\n<li><strong>Chemical products<\/strong>:\u00a0Measuring the flow rate of acids, chlorides, overheated water, etc.<\/li>\n<li><strong>Pharmaceutical sector<\/strong>:\u00a0Demineralised water system processes, etc.<\/li>\n<li><strong>Automotive<\/strong>,\u00a0<strong>agri-food<\/strong>, <strong>energy<\/strong>, etc.<\/li>\n<\/ul>\n<p>\n<\/div><\/div><\/div><br \/>\n<span style=\"color: #000000;\"><em>Downmoad\u00a0<a style=\"color: #000000;\" href=\"\/\/www.ultraflux.net\/wp-content\/uploads\/2021\/09\/UF_821_En.pdf\">Uf 821<\/a>\u00a0datasheet.<\/em><\/span><br \/>\n<span style=\"color: #000000;\"> <em>Click the following link for our explosion-proof model: <a style=\"color: #000000;\" title=\"Uf 841\" href=\"\/\/www.ultraflux.net\/en\/products\/flowmeters-atex-certified\/uf-841\/\" target=\"_blank\" rel=\"noopener noreferrer\">Uf 841<\/a>.<\/em><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Uf 821 flow meter is used to measure the flow of liquids in full pipe up to a diameter of 10,000 mm.
