Hydrometer. Computer artwork of a hydrometer floating in a liquid. A hydrometer is an instrument that uses buoyancy to measure the density of a liquid. It consists of a weighted tube that floats vertically in the liquid. The specific gravity (density) of the liquid is determined by comparing the scale on the tube with the level at which it floats in the liquid | |
