The MetCCUS team created an overview of existing datasets and liquid CO2-flow facilities to investigate how different types of flow meters (e.g. Coriolis, ultrasonic) are calibrated with pure CO2 and CO2-rich mixtures at various flow rates, as well as the transferability to water calibrations. It was found that a small number of SI-traceable calibrations of flow meters with liquid CO2 at the small scale have been conducted. At large scale, there is still a lack of industrial liquid CO2 test and calibration facilities.
Potential layouts of liquid, dense, and supercritical test facilities are also explored, both at small and large scale.
The last two chapters study the estimation of test facility calibration uncertainty and the operational considerations for liquid CO2 conditions, as several CO2-specific safety issues may arise.
