Sierra Instruments has announced the release of a new infographic explaining why mass flow controllers based on capillary thermal mass flow technology provide more accurate mass flow data than volumetric flow devices for industrial gas mass flow control applications.
Over 80% of all industrial processes–such as those involving chemical reactions, combustion, respiration, pharmaceutical, and HVAC– require direct mass flow control and measurement of gasses, not volumetric flow rate, to ensure the quality and efficiency of their process.
Common process gases like air, argon (Ar), carbon dioxide (CO2), nitrogen (N2), oxygen (O2), follow the ‘Ideal Gas Law.’ While not all gases are ‘ideal,’ these common gases work on the principle that when temperature or pressure changes in an application, the density changes for a fixed volume of gas.
