Optimizing CO₂ measurement with accurate flowmeters

As sustainability targets intertwine with financial accountability, the demand for accurate high-pressure CO₂ measurement has surged across industries. Coriolis flowmeters have become the preferred solution thanks to their precision, particularly in custody transfer applications where accuracy is paramount.

However, designing a new CO₂ measurement system involves unique challenges that must be carefully addressed.

Accurate measurement of CO₂ can be complicated due to its variable phases under different pressure and temperature conditions. CO₂ can exist as a gas, liquid, solid or even a supercritical fluid, each of which exhibits different density and flow characteristics. This variability demands proper process design, flowmeter selection, sizing and commissioning to ensure the desired measuring accuracy across the entire range of conditions encountered in CCUS processes. This whitepaper focuses on how to correctly address these challenges to ensure the successful and reliable CO₂ flow measurement.
