Density meter

A density meter, also known as a densometer, is a device that measures the density. Density is usually abbreviated as either \"\\rho or \"D\". Typically, density either has the units of \"{\\displaystyle or \"{\\displaystyle. The most basic principle of how density is calculated is by the formula:
\"{\\displaystyle
Where:
\"\\rho = the density of the sample.
\"m\" = the mass of the sample.
\"V\" = the volume of the sample.
Many density meters can measure both the wet portion and the dry portion of a sample. The wet portion comprises the density from all liquids present in the sample. The dry solids comprise solely of the density of the solids present in the sample.
A density meter does not measure the specific gravity of a sample directly. However, the specific gravity can be inferred from a density meter. The specific gravity is defined as the density of a sample compared to the density of a reference. The reference density is typically of that of water.
