Air is "pushed" into the open end of a barometer when the pressure is higher, meaning the mercury closer to the closed end of the barometer - where the pressure is measured - will rise.

A barometer consists of a glass tube filled with mercury or water, sealed at one end and open at the other. The open end is submerged in a dish of mercury or water to measure air pressure. The height of the liquid in the tube changes with changes in atmospheric pressure.
A mercury barometer is a device used to measure atmospheric pressure. It consists of a glass tube filled with mercury, with one end submerged in a mercury bath. Changes in atmospheric pressure cause the level of mercury in the tube to rise or fall, which can be used to determine the current pressure readings.
To make a record of the air pressure and how it's changing, and aneroid is connected connected with a device that records air pressure, making it an aneroid barograph. An aneroid is a flexible metal bellow that has been tightly sealed after having some air removed. Higher atmospheric pressures squeeze the metal bellows while lower pressures allow it to expand. The aneroid barograph consists of a slowly rotating cylinder with paper on it that can give up to a week's worth of air pressure records before new paper is needed. As you can see in the graphic above, a pen at the end of a lever attached to the aneroid moves up and down according to pressure changes and records the pressure on the paper wrapped around the cylinder.The aneroid barometer has some advantages over a Mercury barometer because it is much smaller and can also record a week's worth of data. The aneroid barometer is the heart of altimeters used in modern aviation.

A barometer is used for measuring atmospheric pressure. The barometer sealed on the top with an open bottom in order to allow air pressure to push down.

Barometers, such as mercury and aneroid barometers, are commonly used to measure atmospheric pressure. Other instruments like electronic pressure sensors and weather balloons equipped with instruments can also measure atmospheric pressure.

A barometer typically consists of a glass tube filled with mercury or a liquid metal, sealed at one end and open at the other. The open end is placed in a container of mercury, allowing atmospheric pressure to push the mercury up the tube. The height of the mercury column is a measure of the atmospheric pressure.
A mercury barometer is a device used to measure atmospheric pressure. It consists of a glass tube filled with mercury, with one end submerged in a mercury bath. Changes in atmospheric pressure cause the level of mercury in the tube to rise or fall, which can be used to determine the current pressure readings.
The Dial was created in 1840.
Dial Award ended in 1998.
The first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:
The function of a manometer is to measure the pressure of a fluid, usually a gas or a liquid. It consists of a sealed tube filled with the fluid being measured, with one end open to the environment and the other end connected to the source of pressure. As the pressure changes, the fluid in the manometer rises or falls, allowing the measurement of the pressure.
A mercury barometer works by, measuring the height of a column of mercury in a sealed tube, supported by the atmospheric pressure.An aneroid barometer measures the amount of distortion of a sealed metal can, due to changes in atmospheric pressure. The equivalent column of mercury supported by a mercury barometer, can then be calibrated in mmHg by comparison.Both instruments do the same job and can be calibrated in Millibars or mmHg, or both.
