It determines the amount of air available, controls production operations and serves as a basis for sizing tools, valves and processes. This is the useful amount of air.<\/div><\/div><\/div><div class=\"sa-faq-block\"><button class=\"sa-faq-trigger\" onclick=\"saToggle(this)\">Mass flow (kg\/s) - what does the compressor &quot;see&quot;? <span>+<\/span><\/button><div class=\"sa-faq-panel\"><div class=\"sa-faq-body\">Mass flow describes how much air is moving through the system as a mass. It depends on pressure and temperature. The same mass can exist in different volumes (small volume at high pressure, large volume at low pressure). This controls the compressor operation and is the &quot;internal gauge&quot; of the device.<\/div><\/div><\/div><div class=\"sa-faq-block\"><button class=\"sa-faq-trigger\" onclick=\"saToggle(this)\">What does the compressor&#039;s &quot;internal gauge&quot; mean? <span>+<\/span><\/button><div class=\"sa-faq-panel\"><div class=\"sa-faq-body\">A centrifugal compressor does not directly measure the volume flow (Nm\u00b3\/h). Instead, it reacts to pressure (bar), temperature, air density (kg\/m\u00b3) and flow resistance. Based on these, a mass flow (kg\/s) is generated.<\/div><\/div><\/div><div class=\"sa-faq-block\"><button class=\"sa-faq-trigger\" onclick=\"saToggle(this)\">Why does mass flow drive the action? <span>+<\/span><\/button><div class=\"sa-faq-panel\"><div class=\"sa-faq-body\">The operation of a centrifugal compressor is based on the energy imparted to the air by the impeller. The energy depends on mass, not volume. In other words, the compressor &quot;accelerates mass&quot;, not volume.<\/div><\/div><\/div><div class=\"sa-faq-block\"><button class=\"sa-faq-trigger\" onclick=\"saToggle(this)\">What does this mean in practice and why is it a problem? <span>+<\/span><\/button><div class=\"sa-faq-panel\"><div class=\"sa-faq-body\">The system may appear to be operating normally, but in reality the air volume delivered (Nm\u00b3\/h) is reduced, the compressors do not reach full load and the control system gives a misleading picture. As a result, the compressors run at part load or blow-off, capacity is not utilized and energy consumption remains high.
