Measuring and controlling fluids near or beyond their supercritical point can be complex. For example, carbon dioxide (CO₂) becomes supercritical at 1070 PSI(a) and 31.1 °C. In this state, physical properties such as density (ρ) and heat capacity (Cp) change rapidly with small variations in pressure or temperature. These fluctuations make accurate mass flow measurement using thermal principles extremely difficult. A Coriolis-based instrument can do the trick.
Application requirements
Processes involving supercritical fluids require precise and reliable flow measurement, regardless of phase changes. Traditional thermal-based flow meters struggle under these conditions because they depend on stable physical properties. A solution is needed that measures the true mass flow of molecules, whether the fluid is in gas phase, liquid phase, or somewhere in between.

Process solution
Bronkhorst’s mini CORI-FLOW mass flow meters provide a solution by measuring the actual mass flow of molecules, unaffected by changes in density or heat capacity. This makes them ideal for applications involving supercritical fluids like CO₂. For control purposes, the flow meter can be combined with a metal-sealed, pressure-actuated control valve, ensuring precise regulation under challenging conditions. Field experience confirms that this approach delivers highly accurate and reliable results.
Why choose the mini CORI-FLOW?
Supercritical fluid processes demand measurement technology that goes beyond conventional methods. By using mini CORI-FLOW mass flow meters, you can achieve consistent, accurate flow control—even under rapidly changing physical conditions—supporting efficiency and reliability in advanced applications.
