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 ...
A gas pycnometer is a laboratory device used for measuring the density—or, more accurately, the volume—of solids, be they regularly shaped, porous or non-porous, monolithic, powdered, granular or in some way comminuted, employing some method of gas displacement and the volume:pressure relationship known as Boyle's law. A gas pycnometer is ...
This in-line section of pipe calculates the percentage of dry solids, wet density or wet and dry mass flow units. When coupled with compatible volumetric flow meters and processing units, this system gives a true value for density and mass flow. [2] The DM3 is a bi-directional unit which allows media to flow continuously through either ends.

Conductivity based TDS meter in a cup of water. The two principal methods of measuring total dissolved solids are gravimetric analysis and conductivity. [4] Gravimetric methods are the most accurate and involve evaporating the liquid solvent and measuring the mass of residues left.
Density (volumetric mass density or specific mass) is a substance's mass per unit of volume.The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used.
