Open the catalog to page 4Mass Flow Meter Model Burner control using Mass Flow Controllers brings many advantages compared to conventional systems, where flow is adjusted through needle valves. When burner orifices get clogged or when gas supply pressure varies, an MFC will automatically adapt to the changed conditions. For the control of relatively large flows with low differential pressure, which is typical for natural gas or CH4, Bronkhorst offers mass flow meters with separate pressure compensated bellows valves. Mass Flow Controller Model MFC’s are often used to make precise and stable mixtures of two or more...
