What Is an Aneroid Barometer?

Barometers have five meanings, the most common of which is barometer.

Although Christian evangelical ministers invented the barometer in 1643, historical literature also suggests that Italian mathematician and astronomer Gasparo Berti inadvertently constructed a water meter between 1640 and 1643. French scientist and philosopher René Descartes described the design of an experiment to determine atmospheric pressure before 1631, but there was no evidence that he had made a working barometer at the time.

On July 27, 1630, Giovanni Battista Baliani gave

The concept of reducing atmospheric pressure to predict stormy weather provides a theoretical basis for weather forecasting equipment called "Weather Glass" or "Goethe Barometer" (named Goethe, a well-known German writer and knowledgeable person developed a simple but effective principle of weather use By Torricelli Ball Barometer). The Frenchman le barometre Liegeois is used by some English speakers. The name reflects the origin of many early weather glasses-the glass blower in Liege, Belgium.

The weather ball barometer consists of a glass container with a sealed body, half of which is water. A narrow spout is attached to the body below the water surface and rises above the water surface. The narrow spout is open to the atmosphere. When the air pressure is lower than the time when the human body is sealed, the water level in the spout will rise above the body's water level; when the air pressure rises, the water level in the spout will fall below the body's water level. This barometer change is easy to make at home.

In February 2013, the use of vacuum pump oil as the working fluid of the barometer led to the birth of a new "world's highest barometer".

(1) Barometer for forecasting weather. It is also sometimes referred to as a sign before something happens.

(2) In school, the psychologist in the class sometimes has to hand this to the teacher, and it is about the good and bad things in the class. The barometer is similar to this report.

(3) The barometer also refers to the central figure of a unit, which influences the whole.

(4) During the construction of the project, the barometer records the weather conditions of each day, and it is possible to view and record the construction content of that day in detail and find the cause of the construction accident.

(5) Barometer is also called barometer, see barometer for details.
