An election is not necessarily an accurate barometer of public opinion. There are other ways in which it makes itself felt, through the press, the forum, discussion, and through every other type of communication..

an instrument for indicating the atmospheric pressure per unit of surface
{n} an instrument used to show the weight of the atmosphere
A device used to measure the pressure of the atmosphere
An instrument for determining the weight or pressure of the atmosphere, and hence for judging of the probable changes of weather, or for ascertaining the height of any ascent
An instrument used to measure atmospheric pressure Two examples are the aneroid barometer and the mercurial barometer
tool for measuring atmospheric pressure

An instrument for determining the pressure of the atmosphere
Instrument for measuring atmospheric pressure
instrument that measures atmospheric pressure Bermuda High: a subtropical anticyclone that occurs over the North Atlantic Ocean biosphere: the zone between the earth and the atmosphere in which most life forms reside black frost: when vegetation is frozen on the inside during a frost in which there is no moisture A black frost will almost always kill the plant boiling point: The temperature at which a substance will change from a liquid state to a gas state The boiling point of water is 100°C and 212°F
a device for measuring atmospheric pressure
An instrument used to measure air pressure The international standard of measurement is the kilopascal although millibars and inches of mercury are also commonly used
Measures atmospheric pressure
A meteorological instrument used to measure atmospheric air pressure (Expressed in millibars)
If something is a barometer of a particular situation, it indicates how things are changing or how things are likely to develop. In past presidential elections, Missouri has been a barometer of the rest of the country. Device used to measure atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude. In the mercury barometer, atmospheric pressure balances a column of mercury, the height of which can be precisely measured. Normal atmospheric pressure is about 14.7 lb per square inch, equivalent to 30 in. (760 mm) of mercury. Other liquids can be used in barometers, but mercury is the most common because of its great density. An aneroid barometer indicates pressure on a dial using a needle that is mechanically linked to a partially evacuated chamber, which responds to pressure changes
An instrument used to measure atmospheric pressure A standard mercury barometer has a glass column about 30 inches long, closed at one end, with a mercury-filled reservoir Mercury in the tube adjusts until the weight of the mercury column balances the atmospheric force exerted on the reservoir High atmospheric pressure forces the mercury higher in the column Low pressure allows the mercury to drop to a lower level in the column An aneroid barometer uses a small, flexible metal box called an aneroid cell The box is tightly sealed after some of the air is removed, so that small changes in external air pressure cause the cell to expand or contract
A sensor that measures barometric pressure
Instrument that measures atmospheric pressure
An instrument for measuring atmospheric pressure and used to predict the weather
Torricellian barometer
A mercury barometer
aneroid barometer
A barometer in which variations in pressure are measured using a partially evacuated capsule whose sides move in and out
barometric
Of or pertaining to atmospheric pressure
mercury barometer
A barometer which indicates the atmospheric pressure by measuring the height of a column of mercury in a vertical, evacuated tube
Barometric
baro
aneroid barometer
n. A barometer in which variations of atmospheric pressure are indicated by the relative bulges of a thin elastic metal disk covering a partially evacuated chamber
aneroid barometer
a barometer that measures pressure without using fluids
aneroid barometer
barometer that measures atmospheric pressure by means of a thin metal disk which covers a partial vacuum
aneroid barometer
meteorological instrument which measures air pressure; a dry barometer as opposed to one which contains liquid such as a mercury barometer (The Surface and Aloft)
aneroid barometer
An instrument designed to measure atmospheric pressure It contains no liquid
aneroid barometer
An instrument for measuring the atmospheric pressure It registers the change in the shape of an evacuated metal cell to measure variations on the atmospheric pressure The aneroid is a thin-walled metal capsule or cell, usually made of phosphor bronze or beryllium copper The scales on the glass cover measure pressure in both inches and millibars
aneroid barometer
A mechanical barometer used to measure air pressure for warnings of changing weather
aneroid barometer
A barometer which measures atmospheric pressure using one or a series of aneroid capsules
aneroid barometer
An instrument used to measure air pressure through the expansion and contraction of a sealed metal chamber which has been partially emptied of air
aneroid barometer
Meteorological instrument which sailors often use to confirm the onset of bad weather Its readings, together with heavy rain, severe rolling, high winds, dark skies and a deep cloud cover, indicate the presence of a storm
aneroid barometer
An instrument used to measure atmospheric pres­sure; based on the movement of the lid of a metal box
aneroid barometer
An instrument built around a metal structure that bends with changing air pressure These changes are recorded on a pointer that moves back and forth across a printed scale
aneroid barometer
A barometer which measures atmospheric pressure using one or a series of aneroid capsules Also called holosteric barometer
aneroid barometer
instrument used to measure atmospheric pressure
aneroid barometer
A device to measure air pressure that uses an aneroid, which is a sealed, flexible metal bellows with some air removed that expands and contracts with air pressure changes
aneroid barometer
an instrument for measuring atmospheric pressure in which a needle, attached to the top of an evacuated box, is deflected as changes in atmospheric pressure cause the top of the box to bend in or out
