barometer

Compare with manometer. An instrument that measures atmospheric pressure. A mercury barometer is a closed tube filled with mercury inverted in a mercury reservoir. The height of the mercury column indicates atmospheric pressure (with 1 atm = 760 mm of mercury). An aneroid barometer consists of an evacuated container with a flexible wall. When atmo...

barometer

The aneroid barometer comprises a partially evacuated corrugated metal box (a), prevented from collapsing by a spring (b). The strain in this spring, proportional to the difference in pressures between the air inside and that outside the box, is amplified by a train of levers (c) that operator a poi...

barometer

barometer (burom'utur) , instrument for measuring atmospheric pressure. It was invented in 1643 by the Italian scientist Evangelista Torricelli, who used a column of water in a tube 34 ft (10.4 m) long. This inconvenient water column was soon replaced by mercury, which is denser than water and r...

Barometer

A barometer is a device for measuring atmospheric pressure and thus determining changes in the weather, the height of mountains, and other phenomena. The basic principle behind the barometer is the discovery in 1643 by Torricelli, that atmospheric pressure might be counterpoised by a column of mercury standing as high in proportion to the thirty-fo...
