As we can accurately measure down to the ppb and ppt-range only very small amounts of tracer gas are required.<br \/>As an example: An injection rate of just 10 ml\/min is sufficient to measure a flow of 300.000 m\u00b3\/h. The downstream concentration then will be 2 ppb.<br \/>Using multiple tracer gases more than one volume flow can be measured at the same time, e.g. for ventilation systems with exhaust one could measure the flow from the right and the flow from the left side.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-33 elementor-top-column elementor-element elementor-element-115ea83\" data-id=\"115ea83\" data-element_type=\"column\" data-e-type=\"column\" data-settings=\"{&quot;_ob_bbad_is_stalker&quot;:&quot;no&quot;,&quot;_ob_teleporter_use&quot;:false,&quot;_ob_column_hoveranimator&quot;:&quot;no&quot;,&quot;_ob_column_has_pseudo&quot;:&quot;no&quot;}\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-31f9374 ob-has-background-overlay elementor-widget elementor-widget-image\" data-id=\"31f9374\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_ob_photomorph_use&quot;:&quot;no&quot;,&quot;_ob_perspektive_use&quot;:&quot;no&quot;,&quot;_ob_poopart_use&quot;:&quot;yes&quot;,&quot;_ob_shadough_use&quot;:&quot;no&quot;,&quot;_ob_allow_hoveranimator&quot;:&quot;no&quot;,&quot;_ob_widget_stalker_use&quot;:&quot;no&quot;}\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"571\" height=\"155\" src=\"https:\/\/tracertech.de\/wp-content\/uploads\/2020\/01\/Tunnelschema.jpg\" class=\"attachment-large size-large wp-image-854\" alt=\"\" srcset=\"https:\/\/tracertech.de\/wp-content\/uploads\/2020\/01\/Tunnelschema.jpg 571w, https:\/\/tracertech.de\/wp-content\/uploads\/2020\/01\/Tunnelschema-300x81.jpg 300w\" sizes=\"(max-width: 571px) 100vw, 571px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-33 elementor-top-column elementor-element elementor-element-c0fdaf0\" data-id=\"c0fdaf0\" data-element_type=\"column\" data-e-type=\"column\" data-settings=\"{&quot;_ob_bbad_is_stalker&quot;:&quot;no&quot;,&quot;_ob_teleporter_use&quot;:false,&quot;_ob_column_hoveranimator&quot;:&quot;no&quot;,&quot;_ob_column_has_pseudo&quot;:&quot;no&quot;}\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-6a2af83 ob-harakiri-inherit ob-has-background-overlay elementor-widget elementor-widget-text-editor\" data-id=\"6a2af83\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_ob_use_harakiri&quot;:&quot;yes&quot;,&quot;_ob_harakiri_writing_mode&quot;:&quot;inherit&quot;,&quot;_ob_postman_use&quot;:&quot;no&quot;,&quot;_ob_perspektive_use&quot;:&quot;no&quot;,&quot;_ob_poopart_use&quot;:&quot;yes&quot;,&quot;_ob_shadough_use&quot;:&quot;no&quot;,&quot;_ob_allow_hoveranimator&quot;:&quot;no&quot;,&quot;_ob_widget_stalker_use&quot;:&quot;no&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Almost in all relevant questions in practice the tracer gas method is superior to the state-of-the-art flow measurement techniques in tunnel using pitot-traverses, averaging pitot tube, anemometers, ultra-sonic etc. Tracer gas tests can be done without any interference of the normal traffic.
