Density is widely used in mass flow computations for custody transfer of supercritical CO2. Determination of density from densitometers is shown to be more reliable than estimation from temperature and pressure. Three types of vibrating element densitometers are described, and typical installation schemes are outlined. Advantages and disadvantages of each densitometer type are reviewed.
