hydrometer
n 1: a measuring instrument for determining the specific gravity
of a liquid or solid [synonym: {hydrometer}, {gravimeter}]

Hydrometer \Hy*drom"e*ter\, n. [Hydro-, 1 -meter: cf. F.
hydrom[`e]tre.]
1. (Physics) An instrument for determining the specific
gravities of liquids, and thence the strength spirituous
liquors, saline solutions, etc.
[1913 Webster]

Note: It is usually made of glass with a graduated stem, and
indicates the specific gravity of a liquid by the depth
to which it sinks in it, the zero of the scale marking
the depth to which it sinks in pure water. Extra
weights are sometimes used to adapt the scale to
liquids of different densities.
[1913 Webster]

2. 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. Hydrometric

HYDROMETER. An instrument for measuring the density of fluids; being
immersed in fluids, as in water, brine, beer, brandy, &c., it determines the
proportion of their densities, or their specific gravities, and thence their
qualities.
2. By, the Act of Congress of January 12, 1825, 3 Story's' Laws U. S.
1976, the secretary of the treasury is authorized, under the direction of
the president of the United States, to adopt and substitute such hydrometer
as he may deem best calculated to promote the public interest, in lieu of
that now prescribed by law, for the purpose of ascertaining the proof of
liquors; and that after such adoption and substitution, the duties imposed
by law upon distilled spirits shall be levied, collected and paid, according
to the proof ascertained by any hydrometer so substituted and adopted.
