Depending on the fluid and flow rate, piping diameters such as 1\/16 inch, 1\/8 inch, 3\/8 inch, and 1\/2 inch are also used. Therefore, it is necessary to choose MFC fittings to match the pipe diameter.<\/p>\n\n\n\n<h4 class=\"wp-block-heading epb-margin-top__8\">Fittings<\/h4>\n\n\n\n<p class=\"epb-margin-top__8 wp-block-paragraph\">VCR type and Swagelok tube fittings are the most popular mass flow controller fittings.<\/p>\n\n\n\n<h5 class=\"wp-block-heading epb-margin-top__8\">VCR Type<\/h5>\n\n\n\n<p class=\"epb-margin-top__8 wp-block-paragraph\">VCR fittings come in male and female types; mass flow controllers usually employ male fittings. Place the metal gasket between the male and female fittings of the MFC and the piping respectively, tighten the nut on the female side by hand, and then tighten it further with a 1\/8 turn with a&nbsp; wrench. (The procedure can be different depending on the&nbsp; gasket material.)<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"A Step-by-Step Guide to Installing a VCR\u00ae Metal Gasket\" width=\"780\" height=\"439\" src=\"https:\/\/www.youtube.com\/embed\/rKMBaJxk4_I?start=36&#038;feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h5 class=\"wp-block-heading\">Swagelok Tube Fittings<\/h5>\n\n\n\n<p class=\"epb-margin-top__8 wp-block-paragraph\">Tube fittings are also called Swagelok fittings, and consist of a fitting, a nut, and a ferrule on the mass flow controller side.

When turned on the power, the thermal sensor will heat up, but the warming up improves stability.<\/li>\n\n\n\n<li>Press zero point reset with the gas completely stopped. For more information, please click here.<\/li>\n\n\n\n<li>Keep signal cables as short as possible. Setting signals and output signals are 0-5V voltage signals. Long cables can cause signal degradation due to voltage drop.<\/li>\n\n\n\n<li>Do not connect Flow rate setting signal COMMON[8],Flow rate output signal COMMON[7], and Power supply COMMON[4] in the power supply unit.<br><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"351\" class=\"wp-image-2527\" style=\"width: 500px;\" src=\"https:\/\/lintec-mfc.co.jp\/en\/wp-content\/uploads\/2024\/03\/MFC-wiring-diagram.png\" alt=\"MFC wiring diagram\" srcset=\"https:\/\/lintec-mfc.co.jp\/en\/wp-content\/uploads\/2024\/03\/MFC-wiring-diagram.png 569w, https:\/\/lintec-mfc.co.jp\/en\/wp-content\/uploads\/2024\/03\/MFC-wiring-diagram-300x211.png 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/li>\n\n\n\n<li>Keep the supply pressure stable to avoid sudden pressure fluctuations. This will minimize the impact of flow control.<\/li>\n\n\n\n<li>When using liquefied gas, please heat the piping to avoid creating the cold spots in the piping. When re-liquefaction occurs, it will cause the rapid pressure fluctuations and lead to the flow instability.<\/li>\n<\/ol>\n\n\n\n<p class=\"epb-margin-top__8 wp-block-paragraph\">These are the key points for using mass flow controllers with higher accuracy.
