Abstract: With the advent of mass measurement, the density measuring instrument has become an extremely important part of the measurement package. Standard correction factors for temperature and compressibility can be used when the physical properties of a product are known, but due to solution mixing and intermolecular adhesion in ethane rich streams, these factors cannot be applied. Therefore, flowing density which can be considered as a factor of temperature and compressibility becomes a direct multiplier in the calculations to obtain mass. With this in mind it becomes obvious the accuracy of the densitometer is as equally important as volumetric accuracy. To achieve this needed accuracy the selection, proper installation, maintenance and provings must be accomplished.
