Density is one of the most prevalent physical property used to classify and characterise fluids, not only in the environmental, cosmetics, pharmaceuticals, and food and beverage industries, but also in hydrocarbon processing industry (HPI). Petroleum products are everywhere in today’s life, and have become almost natural parts of the modern world. Numerous products used on a daily basis are derived from petroleum, such as all kinds of fuels and oils, or the wide range of petrochemicals (solvents, plastics, synthetic fibers, etc.) The raw material, crude oil, and its refinery products are complex mixtures of various carbon hydroxides that are usually characterised through their physical properties, including the density value. Used in conjunction with the specific-industry API Gravity scale*, its accurate and precise measurement is necessary for converting the measured volumes into volumes at reference temperatures (15°C; 20°C and 60°F).
