This course will detail the importance of knowing the density of petroleum products and the applications of density in everyday petroleum operations. We will provide you real-life examples and scenarios vital to your daily operations in fuel terminals, fuel sales, distribution, trading, and even quality assurance.

Accurate determination of the density, relative density (specific gravity), or API gravity of petroleum and its products is necessary for the conversion of measured volumes to volumes or masses, or both, at the standard reference temperature during custody transfer.

This test method is most suitable for determining the density, relative density (specific gravity), or API gravity of low viscosity liquids by allowing sufficient time for the hydrometer to reach equilibrium, and for opaque liquids by employing a suitable meniscus correction.

When used in connection with bulk oil measurements, volume correction errors are minimized by observing the hydrometer reading at a temperature close to that of the bulk oil temperature.

Density, relative density (specific gravity), or API gravity is a factor governing the quality and pricing of crude petroleum. However, this property of petroleum is an uncertain indication of its quality unless correlated with other properties.

Density is an important quality indicator for automotive, aviation and marine fuels, where it affects storage, handling and combustion.
