Density

Density is the absolute relationship between mass and volume at a stated temperature. The SI unit is kg/m 3 at a reference temperature, typically 15°C.

For fuel oils, density is required for quantity calculations and also to determine the optimum size of gravity disc for the centrifuge. Density also gives an indication of other fuel characteristics, including specific energy and ignition quality (CCAI).

From a commercial perspective, the measurement of density is essential as residual fuel is supplied by volume but ordered and priced by weight. If the actual value is less than that stated, there will be a proportional shortfall in the quantity of product supplied.  From a technical perspective, without density the incorrect gravity disc may be selected for setting the traditional purifier.
