most accurate with low uncertainty under real process conditions. To achieve this, we operate more than 120 calibration facilities for volume flow, mass flow, level, temperature, density and pressure to (wet-) calibrate any device we manufacture. For example, every flowmeter is wet-calibrated using water or air as standard before leaving our facilities. We can also provide customer specific calibration such as:<\/p>\n<ul>\n<li>Carry out multipoint calibrations<\/li>\n<li>Vary different parameters such as temperatures, viscosities, pressures etc.<\/li>\n<li>Use the actual medium or similar<\/li>\n<li>Build or emulate customer-specific flow geometries<\/li>\n<li>Use piping provided by the customer<\/li>\n<\/ul>\n<p>For calibration we only use direct comparison of measurands (e.g. we calibrate our Coriolis mass flowmeters with a gravimetric weighing system). Our calibration rigs are the most accurate used in measuring device production worldwide: the accuracy of the reference is usually 5 to 10 times better than that of the meter under test.<\/p>\n<p>This goes for small as well as for very large sizes: KROHNE operates the world\u2019s most precise volumetric calibration rig for flowmeters up to DN 3000 (120&#8243;*) with a certified accuracy of 0.013 %. The reference vessel is a 44 m (144 ft*) high tank containing almost \u00bd million litres (132,000 gal*) of water which allows for a maximum flow rate of 30,000 m\u00b3\/h (7,925,000 gal\/h*).<\/p>\n<\/div><\/section><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-pgr9-68f87742d7745ba80216c1148ed183cb\">\n#top .av-special-heading.av-pgr9-68f87742d7745ba80216c1148ed183cb{\npadding-bottom:10px;\n}\nbody .av-special-heading.av-pgr9-68f87742d7745ba80216c1148ed183cb .av-special-heading-tag .heading-char{\nfont-size:25px;\n}\n.av-special-heading.av-pgr9-68f87742d7745ba80216c1148ed183cb .av-subheading{\nfont-size:15px;\n}\n<\/style>\n<div  class='av-special-heading av-pgr9-68f87742d7745ba80216c1148ed183cb av-special-heading-h2 blockquote modern-quote  avia-builder-el-9  el_after_av_textblock  el_before_av_textblock '><h2 class='av-special-heading-tag'  itemprop=\"headline\"  >Certified technology for fiscal <span class='special_amp'>&amp;<\/span> custody transfer applications<\/h2><div class=\"special-heading-border\"><div class=\"special-heading-inner-border\"><\/div><\/div><\/div><br \/>\n<section  class='av_textblock_section av-4my20-12-887d783b478514201d17ea4ed4221335 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>Our meters can be calibrated and certified according to various standards such as OIML, API, Measurement Instruments Directive (MI 001, 002, 004, 005), GOST, etc. All our calibration facilities comply to the traceability requirements according to ISO.<\/p>\n<p>Regular inspections by national metrology institutes, round robin tests and alignments with national and international metrological standards according to ISO 9000 and EN 45000 guarantee the quality and comparability of our calibration rigs.

><div class='avia_textblock'  itemprop=\"text\" ><p>The development calibration rig put into operation in 2009 is available for measurements of air-volume flows up to 2500 m3\/h. Calibration is performed using two turbines that are regularly traced back to the measurement standard of a national body to ensure measuring accuracy. Figure 3.2 shows the measuring section and references of the large air calibration rig.<\/p>\n<p>The production of the OPTISWIRL vortex flowmeter series represents the second large product line at the Duisburg site. For the calibration of the vortex flowmeters alone, two revolver calibration rigs were built. Through the rotation of the revolver, the measuring sections necessary to calibrate different nominal sizes can be rotated to the level of the measuring section without long conversion times. Calibration takes place with water at flow rates up to 575 m3 \/h using electromagnetic flowmeters. Long inlet runs in front of the meter under test and specially fabricated inlet runs for the references guarantee precise measuring conditions with long-term stability. The flow points are started and measurement data is recorded automatically. The measurement data are stored in a database. Figure 3.3 depicts the large revolver calibration rig used to calibrate vortex flowmeters.<\/p>\n<p>Flowmeters in the lower flow range can be calibrated with the help of the small air calibration rig up to 500 m\u00b3\/h under normal conditions and 8 barg at temperatures up to 90 \u00b0C. Critical nozzles are used as reference. They are regularly traced back to national and international standards. In addition to being able to calibrate the flowmeters in a vertical or horizontal position, meters of varying physical measuring principles can be calibrated.<\/p>\n<\/div><\/section><\/div>\n<\/p>\n<\/div><\/div><\/div><!-- close content main div --><\/div><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-4rwig-9-32a6e9207963814e44034ba28114151d\">\n.avia-section.av-4rwig-9-32a6e9207963814e44034ba28114151d{\nbackground-color:#f8f8f8;\nbackground-image:unset;\n}\n<\/style>\n<div id='av_section_5'  class='avia-section av-4rwig-9-32a6e9207963814e44034ba28114151d main_color avia-section-default avia-no-border-styling  avia-builder-el-19  el_after_av_section  avia-builder-el-last  avia-bg-style-scroll container_wrap fullsize'  ><div class='container av-section-cont-open' ><div class='template-page content  av-content-full alpha units'><div class='post-entry post-entry-type-page post-entry-17'><div class='entry-content-wrapper clearfix'>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-4qjwg-8-8e2f6e21e8f7d56fbc9a51e1646b2f85\">\n.flex_column.av-4qjwg-8-8e2f6e21e8f7d56fbc9a51e1646b2f85{\nborder-radius:0px 0px 0px 0px;\npadding:28px 0 0 38px;\n}\n<\/style>\n<div  class='flex_column av-4qjwg-8-8e2f6e21e8f7d56fbc9a51e1646b2f85 av_one_third  avia-builder-el-20  el_before_av_one_third  avia-builder-el-first  first flex_column_div av-animated-generic bottom-to-top  '     ><p>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-1m908-02846ad9dcefcee19f5120c957355f7e\">\n#top .av-special-heading.av-1m908-02846ad9dcefcee19f5120c957355f7e{\npadding-bottom:10px;\n}\nbody .av-special-heading.av-1m908-02846ad9dcefcee19f5120c957355f7e .av-special-heading-tag .heading-char{\nfont-size:25px;\n}\n.av-special-heading.av-1m908-02846ad9dcefcee19f5120c957355f7e .av-subheading{\nfont-size:15px;\n}\n<\/style>\n<div  class='av-special-heading av-1m908-02846ad9dcefcee19f5120c957355f7e av-special-heading-h2 blockquote modern-quote  avia-builder-el-21  el_before_av_textblock  avia-builder-el-first '><h2 class='av-special-heading-tag'  itemprop=\"headline\"  >Influences in practical use<\/h2><div class=\"special-heading-border\"><div class=\"special-heading-inner-border\"><\/div><\/div><\/div><br \/>\n<section  class='av_textblock_section av-4my20-7-d39ce64b5d36be9c3b5c93831e22b3f6 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>When you consider the calibration values of a flowmeter, ideally they should not deviate from the measuring values in the application.<\/p>\n<\/div><\/section><br \/>\n<div  class='avia-button-wrap av-jl3l62vm-a81f2e12ae5be5c1f17d227d0d2fb015-wrap avia-button-left  avia-builder-el-23  el_after_av_textblock  avia-builder-el-last '><a href='https:\/\/cmp.krohne.com\/calibration\/influences\/'  class='avia-button av-jl3l62vm-a81f2e12ae5be5c1f17d227d0d2fb015 avia-icon_select-no avia-size-medium avia-position-left avia-color-theme-color'  ><span class='avia_iconbox_title' >Learn more<\/span><\/a><\/div><\/p><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-4qjwg-6-ff82604400a9f66acc3e860db84cb303\">\n.flex_column.av-4qjwg-6-ff82604400a9f66acc3e860db84cb303{\nborder-radius:0px 0px 0px 0px;\npadding:28px 0 0 38px;\n}\n<\/style>\n<div  class='flex_column av-4qjwg-6-ff82604400a9f66acc3e860db84cb303 av_one_third  avia-builder-el-24  el_after_av_one_third  el_before_av_one_third  flex_column_div av-animated-generic bottom-to-top  '     ><p>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-ys6c-ca3f0fe8db8214e01bbe8efda21fad5b\">\n#top .av-special-heading.av-ys6c-ca3f0fe8db8214e01bbe8efda21fad5b{\npadding-bottom:10px;\n}\nbody .av-special-heading.av-ys6c-ca3f0fe8db8214e01bbe8efda21fad5b .av-special-heading-tag .heading-char{\nfont-size:25px;\n}\n.av-special-heading.av-ys6c-ca3f0fe8db8214e01bbe8efda21fad5b .av-subheading{\nfont-size:15px;\n}\n<\/style>\n<div  class='av-special-heading av-ys6c-ca3f0fe8db8214e01bbe8efda21fad5b av-special-heading-h2 blockquote modern-quote  avia-builder-el-25  el_before_av_textblock  avia-builder-el-first '><h2 class='av-special-heading-tag'  itemprop=\"headline\"  >References and measurement standards<\/h2><div class=\"special-heading-border\"><div class=\"special-heading-inner-border\"><\/div><\/div><\/div><br \/>\n<section  class='av_textblock_section av-4my20-5-5760b8258c653262e10493c174215df9 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>Calibration usually takes place with the help of a &#8220;more accurate&#8221; measuring device.
