length, mass, thermal energy, noise level velocity etc. When it comes to flowmeters it is usually the signal of one pulse output, where one pulse stands for one flowed through mass or volume, or a

comparison of measurements followed by a written report of the results, the so-called systematic error of measurement. The resulting document is generally referred to as a calibration certificate or calibration protocol. Examples of calibration certificates can be found on page 26. The result of the comparison when calibrating is expressed as a difference, i.e. the deviation of the measurement of the device to be calibrated from the more accurate reference device. This difference can be expressed as a deviation in the unit of the quantity measured or as a percentage. The reference is then either the measured value or the measuring range end value.<\/p>\n<p>Typically, during calibration the measurement of the meter under test is compared to that of an identical or similar, more accurate measuring device. The example of the beam balance clearly demonstrates this: the left-hand side holds a 1 kg weight to be calibrated and the right-hand side holds a very accurate 1 kg weight. The difference in mass of the two weights results in a mass-scaled height difference between the two balance trays.<\/p>\n<\/div><\/section><\/p><\/div>\n\n<\/div><\/div><\/div><!-- close content main div --><\/div><\/div><div id='av_section_5'  class='avia-section av-4rwig-109c741a41c85490012544e753bfbf7c main_color avia-section-default avia-no-shadow  avia-builder-el-18  el_after_av_section  el_before_av_section  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-10'><div class='entry-content-wrapper clearfix'>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-4qjwg-a55ddf3c5301e5aeb4c335874d9662ff\">\n.flex_column.av-4qjwg-a55ddf3c5301e5aeb4c335874d9662ff{\nborder-radius:0px 0px 0px 0px;\npadding:0 0 0 38px;\n}\n<\/style>\n<div  class='flex_column av-4qjwg-a55ddf3c5301e5aeb4c335874d9662ff av_one_half  avia-builder-el-19  el_before_av_one_half  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-8ne-b2a8fca9a9522673765b8ad647259c6a\">\n#top .av-special-heading.av-8ne-b2a8fca9a9522673765b8ad647259c6a{\npadding-bottom:10px;\n}\nbody .av-special-heading.av-8ne-b2a8fca9a9522673765b8ad647259c6a .av-special-heading-tag .heading-char{\nfont-size:25px;\n}\n.av-special-heading.av-8ne-b2a8fca9a9522673765b8ad647259c6a .av-subheading{\nfont-size:15px;\n}\n<\/style>\n<div  class='av-special-heading av-8ne-b2a8fca9a9522673765b8ad647259c6a av-special-heading-h2 blockquote modern-quote  avia-builder-el-20  el_before_av_textblock  avia-builder-el-first '><h2 class='av-special-heading-tag'  itemprop=\"headline\"  >Flowmeter calibration<\/h2><div class=\"special-heading-border\"><div class=\"special-heading-inner-border\"><\/div><\/div><\/div><br \/>\n<section  class='av_textblock_section av-4my20-652256a62071118ce7e55a7e57850585 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>Flowmeter calibration generally takes place under fixed medium conditions like temperature, pressure, conductivity and volume flow as well as fixed ambient conditions such as pressure, temperature and humidity. What is calibrated is a pulse or frequency output, a 4-20 mA output, less frequently the display or bus signals. Depending on the accuracy required for the calibration, various processes including reference meters and gravimetric or volumetric liquid flow standard measurement calibration rigs may be used where the reference should have between three to five times less measurement uncertainty than the device to be calibrated. Reference meters are often used for calibration when similar measurement variables (e.g. variable area flowmeters) or measuring devices with defined error limits are calibrated, see Fig 1.2.<\/p>\n<\/div><\/section><\/p><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-4jk9a-ea988722a56d5f4a46c98f965a64d410\">\n.flex_column.av-4jk9a-ea988722a56d5f4a46c98f965a64d410{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 38px;\n}\n<\/style>\n<div  class='flex_column av-4jk9a-ea988722a56d5f4a46c98f965a64d410 av_one_half  avia-builder-el-22  el_after_av_one_half  el_before_av_one_half  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-jl3lm9qy-00404dcaa0cb325677978b7168479a31\">\n.avia-image-container.av-jl3lm9qy-00404dcaa0cb325677978b7168479a31 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-jl3lm9qy-00404dcaa0cb325677978b7168479a31 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-jl3lm9qy-00404dcaa0cb325677978b7168479a31 av-styling- avia-align-center  avia-builder-el-23  el_before_av_textblock  avia-builder-el-first '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><a href=\"https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1.png\" data-srcset=\"https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1.png 779w, https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1-300x82.png 300w, https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1-768x209.png 768w, https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1-705x192.png 705w, https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1-450x122.png 450w\" data-sizes=\"(max-width: 779px) 100vw, 779px\" class='avia_image'  aria-label='Flowmeter-and-reference'><img decoding=\"async\" class='wp-image-109 avia-img-lazy-loading-not-109 avia_image ' src=\"https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1.png\" alt='Flowmeter-and-reference' title='Flowmeter-and-reference'  height=\"212\" width=\"779\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1.png 779w, https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1-300x82.png 300w, https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1-768x209.png 768w, https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1-705x192.png 705w, https:\/\/cmp.krohne.com\/calibration\/wp-content\/uploads\/sites\/4\/2018\/08\/Flowmeter-and-reference-1-450x122.png 450w\" sizes=\"(max-width: 779px) 100vw, 779px\" \/><\/a><\/div><\/div><\/div><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-jl3lns6h-60e36897594062547b0ab5ce472f1631\">\n#top .av_textblock_section.av-jl3lns6h-60e36897594062547b0ab5ce472f1631 .avia_textblock{\nfont-size:12px;\n}\n<\/style>\n<section  class='av_textblock_section av-jl3lns6h-60e36897594062547b0ab5ce472f1631 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>Figure 1.2: Flowmeter and reference<\/p>\n<\/div><\/section><\/p><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-4qjwg-a55ddf3c5301e5aeb4c335874d9662ff\">\n.flex_column.av-4qjwg-a55ddf3c5301e5aeb4c335874d9662ff{\nborder-radius:0px 0px 0px 0px;\npadding:0 0 0 38px;\n}\n<\/style>\n<div  class='flex_column av-4qjwg-a55ddf3c5301e5aeb4c335874d9662ff av_one_half  avia-builder-el-25  el_after_av_one_half  el_before_av_one_half  first flex_column_div av-animated-generic bottom-to-top  column-top-margin'     ><section  class='av_textblock_section av-4my20-652256a62071118ce7e55a7e57850585 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>However, instead of flowmeters, flow calibration rigs are now used as the reference for precision calibration. In this case the flowing mass or volume is displayed via a mass and density measurement or volume measurement. This ultimately enables the most accurate measurement of the volume or mass of flowing products. Here, we distinguish between calibration rigs based on either the volumetric or gravimetric principle, see Fig 1.3 and Fig 1.4.<\/p>\n<p>In the case of volumetric calibration rigs the volume flowing through a meter under test is compared to the reference volume of a cylinder, tower or tank with an interior volume that is precisely known. The reference volume can be determined geometrically or by volumetric measurement in intervals using reference volumes. So-called piston prover systems are also based on the volumetric principle. With these systems, a known volume of a test product is pressed out by a propelled piston, passing through the meter under test into a storage tank. When the piston is pulled back, further measurements are made possible.<\/p>\n<p>When it comes to gravimetric calibration rigs, the volume (or mass) flowing through the meter under test is compared to the indicator on a scale. The reference volume is then determined using the density of the product and by taking into account the various influencing variables on the measuring process. In most cases, testing is done in flying start-stop mode, whereby a diverter routes the product into the scale, or in standing start-stop mode. The calibration of the scales is typically done using stainless steel standard weights in accuracy class F2.<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\"

devices are calibrated to gather information about the current behaviour or condition of the measuring device at the time of calibration. Any calibration is always tied to the existing temporal and local conditions. Prognoses about the behaviour of the measuring device in the application can be made, for example, based on experience or farther-reaching tests.<\/p>\n<p>In regards to the information gathered about the measuring device during calibration, a distinction is generally made between industrial and legal metrology. In the field of industrial metrology, i.e. for use in the food and beverage industry, pharmaceuticals, the oil and gas industry for mixing and dosing processes, feeding plants etc., requires measuring devices that measure the mass flow as stable as possible and without fluctuations. On top of that, the devices must be able to display the same values over longer periods of time, i.e. they must have good long-term stability. This ensures high process stability.<\/p>\n<p>In the field of legal metrology, i.e. anywhere goods must be billed, the measuring devices must measure within the maximum permissible errors and be regularly recalibrated, which is called verification (see also calibration law and calibration ordinance).<\/p>\n<\/div><\/section><\/p><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-4jk9a-ea988722a56d5f4a46c98f965a64d410\">\n.flex_column.av-4jk9a-ea988722a56d5f4a46c98f965a64d410{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 38px;\n}\n<\/style>\n<div  class='flex_column av-4jk9a-ea988722a56d5f4a46c98f965a64d410 av_one_half  avia-builder-el-36  el_after_av_one_half  el_before_av_one_half  flex_column_div av-animated-generic bottom-to-top  '     ><p><section  class='av_textblock_section av-4my20-652256a62071118ce7e55a7e57850585 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>With the introduction of the Measuring instruments directive 2004\/22\/EC in 2004, custody transfer was standardised on a European level and it became legal in Germany on 30 October 2006.

A measuring device that has been evaluated for conformity obtains a declaration of conformity from the manufacturer and can now be made available to an end user (released).<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-4jk9a-ea988722a56d5f4a46c98f965a64d410\">\n.flex_column.av-4jk9a-ea988722a56d5f4a46c98f965a64d410{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 38px;\n}\n<\/style>\n<div  class='flex_column av-4jk9a-ea988722a56d5f4a46c98f965a64d410 av_one_half  avia-builder-el-41  el_after_av_one_half  avia-builder-el-last  flex_column_div av-animated-generic bottom-to-top  column-top-margin'     ><section  class='av_textblock_section av-4my20-652256a62071118ce7e55a7e57850585 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>Although these measuring devices have been governed in accordance with national law by way of domestic type approvals and calibration, measuring devices putted into use after the Measuring Instruments Directive are subject to a conformity assessment. Calibration is carried out by the calibration office or a nationally recognised test body. Each country has jurisdiction over this task and it is valid for all measuring devices that are recalibrated once the reverification period has expired as well as for &#8220;first calibrations&#8221; of measuring devices not subject to European law such as cooling measurements. All measuring devices not mentioned in the European measuring instruments directive as well as features specific to each country, such as the length of the calibration period and exceptions to mandatory verification, are subject to national law.<\/p>\n<\/div><\/section><\/div>\n\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-b72f8a319b9cc9e01807250c2e8c8bce\">\n.avia-section.av-4rwig-b72f8a319b9cc9e01807250c2e8c8bce{\nbackground-color:#f8f8f8;\nbackground-image:unset;\n}\n<\/style>\n<div id='av_section_7'  class='avia-section av-4rwig-b72f8a319b9cc9e01807250c2e8c8bce main_color avia-section-default avia-no-border-styling  avia-builder-el-43  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-10'><div class='entry-content-wrapper clearfix'>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-4qjwg-622d8aebf768a7777b35522c00da7636\">\n.flex_column.av-4qjwg-622d8aebf768a7777b35522c00da7636{\nborder-radius:0px 0px 0px 0px;\npadding:28px 0 0 38px;\n}\n<\/style>\n<div  class='flex_column av-4qjwg-622d8aebf768a7777b35522c00da7636 av_one_third  avia-builder-el-44  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-2c38u-c329c9b327bdf16af35b4fa009930870\">\n#top .av-special-heading.av-2c38u-c329c9b327bdf16af35b4fa009930870{\npadding-bottom:10px;\n}\nbody .av-special-heading.av-2c38u-c329c9b327bdf16af35b4fa009930870 .av-special-heading-tag .heading-char{\nfont-size:25px;\n}\n.av-special-heading.av-2c38u-c329c9b327bdf16af35b4fa009930870 .av-subheading{\nfont-size:15px;\n}\n<\/style>\n<div  class='av-special-heading av-2c38u-c329c9b327bdf16af35b4fa009930870 av-special-heading-h2 blockquote modern-quote  avia-builder-el-45  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-4my20-652256a62071118ce7e55a7e57850585 '   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-47  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-f0f12ff6653b45a096b1a6a750567541\">\n.flex_column.av-4qjwg-f0f12ff6653b45a096b1a6a750567541{\nborder-radius:0px 0px 0px 0px;\npadding:28px 0 0 38px;\n}\n<\/style>\n<div  class='flex_column av-4qjwg-f0f12ff6653b45a096b1a6a750567541 av_one_third  avia-builder-el-48  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-1ke3m-fe898897aaf6839ff448d3ac0e20c93d\">\n#top .av-special-heading.av-1ke3m-fe898897aaf6839ff448d3ac0e20c93d{\npadding-bottom:10px;\n}\nbody .av-special-heading.av-1ke3m-fe898897aaf6839ff448d3ac0e20c93d .av-special-heading-tag .heading-char{\nfont-size:25px;\n}\n.av-special-heading.av-1ke3m-fe898897aaf6839ff448d3ac0e20c93d .av-subheading{\nfont-size:15px;\n}\n<\/style>\n<div  class='av-special-heading av-1ke3m-fe898897aaf6839ff448d3ac0e20c93d av-special-heading-h2 blockquote modern-quote  avia-builder-el-49  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-4my20-652256a62071118ce7e55a7e57850585 '   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.
