    en.wikipedia.org/wiki/Hydrometry

    Hydrometry is the monitoring of the components of the hydrological cycle including rainfall, groundwater characteristics, as well as water quality and flow characteristics of surface waters. [1]

    The hydrometer sinks deeper in low-density liquids such as kerosene, gasoline, and alcohol, and less deep in high-density liquids such as brine, milk, and acids. It is usual for hydrometers to be used with dense liquids to have the mark 1.000 (for water) near the top of the stem, and those for use with lighter liquids to have 1.000 near the bottom.

    The hydrometer is then removed, wiped dry, and placed in the liquid whose density is to be determined. A weight (x) sufficient to sink the hydrometer to the same marked point is placed in the pan. The density (D) of the second liquid is then given by D = (W + x) / (W + w). [1] The Fahrenheit hydrometer can be made of either glass or metal.

    Weather stations typically have these following instruments: . Thermometer for measuring air and sea surface temperature; Barometer for measuring atmospheric pressure; Hygrometer for measuring humidity

  7. Baumé scale - Wikipedia

    en.wikipedia.org/wiki/Baumé_scale

    The Baumé scale is a pair of hydrometer scales developed by French pharmacist Antoine Baumé in 1768 to measure density of various liquids. The unit of the Baumé scale has been notated variously as degrees Baumé, B°, Bé° and simply Baumé (the accent is not always present). One scale measures the density of liquids heavier than water and ...

    The only reference to modern history claims (without giving a reference) that the hydrometer appears in the works of Jacques Alexandre César Charles, who was born in 1746, but a London instrument maker, John Clarke, was marketing hydrometers in 1725, when they were in use by the Excise authorities to measure the strengths of spirits, and there ...

    The success of the device caused his name to be immortalised in an Act of Parliament: Sikes' Hydrometer Act 1816 (56 Geo. 3. c. 140). From 1816 until 1980 the hydrometer was the standard used in the UK to measure the alcohol proof of spirits, and from 1846 in Canadian law. [4]
