AREOMETER Meaning and
Definition
-
An areometer is an instrument used to measure the specific gravity or density of a liquid, typically in the field of science and industry. It consists of a narrow glass tube with a weighted bulb at the bottom and a graduated scale on the stem. The principle behind its operation depends on Archimedes' principle of buoyancy, which states that a body immersed in a fluid experiences an upward force equal to the weight of the fluid displaced by the body.
To use an areometer, it is gently lowered into the liquid being tested, allowing it to freely float in an upright position. The depth to which the instrument sinks in the liquid determines its specific gravity. The graduated scale on the stem of the areometer displays the specific gravity readings, enabling accurate measurement and comparison of densities between different liquids.
Areometers are commonly employed in various industrial applications, such as the petroleum industry to measure the density of crude oil or refined products, in winemaking to determine sugar content in grape must, and in the chemical industry for evaluating the concentration of solutions.
The design of an areometer may vary depending on the specific purpose, but most areometers are made of glass, ensuring transparency and resistance to corrosion from the liquids being tested. Some areometers also feature a thermometer to account for variations in temperature, which can affect the accuracy of density readings.

Etymology of AREOMETER
The word "areometer" comes from the combination of two Greek roots: "areos", meaning "air" or "gas", and "metron", meaning "measure" or "instrument". The term was formed by English natural philosopher Edward Nairne in the late 18th century to refer to an instrument used for measuring the specific gravity of gases.
