It's known as an aneroid barometer. It works by the difference in pressure causing a partially flattened tube which is wound into a coil to straighten out. The movement is converted to circular motion by a series of gears. the central shaft has a needle attached which indicates the pressure.

What kind of liquid is found in a barometer?
Mercury is the liquid typically found in a barometer. It is used to measure atmospheric pressure due to its density and ability to rise and fall within the tube as pressure changes.
An aneroid barometer is different from a mercury barometer in that it does not contain?
An aneroid barometer does not contain mercury. Instead, it uses a small, flexible metal box called an aneroid cell to measure air pressure changes. Aneroid barometers are safer and more portable than mercury barometers.
Structure of barometer?
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.
What is in a thermometer and a barometer?
A thermometer measures temperature - most are now electric but they used to have alcohol or mercury in them. A barometer measures air pressure - they are now electric but used to have air in them (in a bellows with a spring).
What is the instrument that measures air pressure without using liquid?
An aneroid barometer is a type of instrument that can measure air pressure without using liquid. It consists of a small, flexible metal box that is partially evacuated and attached to a mechanical linkage that can record changes in atmospheric pressure.
What is an aneroid barometer called?
Well, an aneroid barometer, is called an aneroid barometer- but, a barometer measures air pressure, and an aneroid barometer is a barometer that contains no liquid.
What is the definition of aneroid?
Containing no liquid; -- said of a kind of barometer., An aneroid barometer.
What devices contain mercury?
Thermometer or barometer
How a barometer can be used to measure the vapor pressure of a liquid?
A mercury thermometer, that is a barometer can be used to measure vapor pressure. Initially, a proper temperature must be recorded. Then the liquid should be injected into the mercury column. This new measurement subtracted from the original will yield the vapor pressure of a liquid.
What liquid metal is found inside of a barometer?
Mercury.

aneroid barometer
What is the liquid in a termometer?
Actually a barometer can be made of just about any liquid with a sufficiently low vapour pressure. For example, most people don't realize that their toilet acts as a barometer. Traditionally barometers were made with Hg, but they could be made with just about any liquid with a low VP.
Which liquid is used in an aneroid barometer a mercury b alcohol c none?
mercury
How did the barometer get its name?
The barometer got its name from a combination of two Greek words: "baros" meaning weight, and "metron" meaning measure. This reflects its function of measuring atmospheric pressure by the weight of the air.
When air pressure goes up the liquid in a mercury barometer goes?
When air pressure goes up, the liquid in a mercury barometer goes down. This is because as air pressure increases, it pushes the mercury in the tube to rise, indicating higher pressure.
