Which gases are embedded in the EL-FLOW® Prestige mass flow meter/controller?

Gas properties vary with temperature and pressure changes. The EL-FLOW Prestige thermal mass flow meter/controller uses the actual measured temperature (and pressure if applicable) for the real-time on-board calculation of the fluid properties. For this reason, the EL-FLOW Prestige mass flow meters and controllers have a database with gas properties embedded in the instrument (“Fluidat-On-Board”). The instrument embeds the following gases:
