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.


How are the Mercury and aneroid barometers alike?

mercury barometers and aneroid barometers both measure air pressure.


How does an aneroid barometer works?

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.


Why can an aneroid barometer measure elevations as well as air pressure?

The aneroid measures elevation and air pressure has an airtight chamber that is sensetive to changes in the air pressures. Hope this helps.


Which type of barometer is most commonly used today?

aneroid
