hydrometer (Noun)
An instrument that floats in a liquid and measures its specific gravity on a scale.

hydrometer (n.)
An instrument for determining the specific gravities of liquids, and thence the strength spirituous liquors, saline solutions, etc.
hydrometer (n.)
An instrument, variously constructed, used for measuring the velocity or discharge of water, as in rivers, from reservoirs, etc., and called by various specific names according to its construction or use, as tachometer, rheometer, hydrometer, pendulum, etc.; a current gauge.

hydrometer
Instrument that floats in a liquid and measures its specific gravity on a scale.

hydrometer
hī-drom′et-ėr, n. an instrument for measuring the density or specific gravity of solids and liquids by flotation, consisting of a weighted glass bulb or hollow metal cylinder with a long stem: a current-gauge.—adjs. Hydromet′ric, -al.—n. Hydrom′etry. [Gr. hydōr, water, metron, a measure.]

hydrometer
An instrument constructed to measure the specific gravities of fluids. That used at sea for testing the amount of salt in the water is a glass tube containing a scale, the bottom of the tube swelling out into two bulbs, of which the lower is laden with shot, which causes the instrument to float perpendicularly, and as it displaces its own weight of water, of course it sinks deeper as the water is lighter, which is recorded by the scale.
