In addition to lactometry (determination of the extent to which a hydrometer sinks), the density of milk can be measured by pycnometry (determination of the mass of a given volume of milk), by hydrostatic weighing of an immersed bulb (e.g. Westphal balance), by dialatometry (measurement of the volume of a known mass of milk) or by measuring the distance that a drop of milk falls through a density gradient column.

Density is the mass per unit volume of a substance. Specific gravity is the density of the substance relative to a standard such as liquid water at 4°C. The density of liquids is monitored by hydrometers, weighing a fixed volume (density balance), the Coriolis method (described in Section 12.2.5), and vibrating methods. Hydrostatic, displacement float, sonic, and radiometric methods are among others also used [4].
