Density is the most common and simplest physical property index for petroleum and petroleum products. The density of petroleum increases with the increase of the contents of carbon, hydrogen and sulfur in its composition, so that the petroleum and petroleum products containing more aromatic hydrocarbons, more colloids and asphaltenes have the highest density, the middle containing more naphthenic hydrocarbons and the smallest containing more alkanes.
Densitometry is a commonly used method for detecting oil density at present, and is based on the Archimedes' law. The sample is brought to a specific temperature, poured into a density measuring cylinder at approximately the same temperature, a suitable densitometer is placed into the sample at the adjusted temperature, and when the densitometer sinks into the liquid petroleum product, a small portion of the liquid is displaced, the densitometer being subjected to the buoyant force of the weight of the liquid displaced by it. According to the Archimedes' law, when the weight of the liquid discharged by the densitometer is equal to the weight of the densitometer itself, i.e. the buoyancy to which the densitometer is subjected is equal to the weight acting on it, the densitometer floats in the petroleum product, in equilibrium. When the temperature reaches equilibrium, the densitometer reading and the sample temperature are read. The observed densitometer readings were converted to standard densities using an oil meter.
Although densitometry is a detection method that can achieve rapid measurement and is simple to operate, it still has many disadvantages, and it is difficult to meet the actual needs of some customers.
