Can a barometer be used as an altimeter?
With a little modification yes.
The principals of design for the Barometer and Altimeter are the same. A sealed capsule expands and contracts with changes in air pressure, this movement is then changed to the movement of a dial to get a scaled reading.
However the Barometer would need its scale changing to read in terms of altitude. This would allow a rudimentary calculation of altitude, however as the air pressure changes, the altitude read on the scale would change.
The Altimeter as used in aircraft also has a small thumb wheel or turntable knob that allows you to set the air pressure to the air pressure of the ground. This makes the scale more accurate, and negates any changes in air pressure.
Barometer is the device used for measuring atmospheric pressure.Whereas,altimeter is the instrument that measures the altitude of the land surface or of any object, such as an airplane.
A barometer and an altimeter.
The barometer became used as an altimeter in early aircraft to measure height above the ground and has been refined to be in every aircraft today.
Usually the instrument used is called a barometer - which could be a closed end manometer or an aneroid barometer. An altimeter actually also measures atmospheric pressures - but for a different purpose.
S(he) uses an altimeter which a kind of airborne barometer.
The altimeter is essentially an aneroid barometer that reads in units of altitude rather than pressure. This is possible by using the standard atmosphere to make the conversion from pressure to altitude.
An instrument for determining elevation, especially an aneroid barometer used in aircraft that senses pressure changes accompanying changes in altitude.
Mainly meteorologists (weathermen), but chemists, engineers, and other scientists may. A barometer is an instrument used to measure pressure. Pilots and almost anyone involved with aviation use it. The altimeter in a plane works basically like a kind of barometer, and the barometric pressures affect the altimeter readings. It's very important to be able to correct for changing pressures, otherwise you could think you are at a higher altitude than you actually are, obviously dangerous.
Using a metric barometer, you should put a magnet in between the two, and the altitude on the altimeter should immediatley go to zero. if it is not at zero, but a negative or positive, you know it is off by that number. Example: -7 ft. ----- This means your altimeter is 7 feet below the accurate number.
An altimeter is sensitive to atmospheric pressure and can show the altitude of the aircraft based on the change in atmospheric pressure from the aircraft ascending and descending. Likewise, a barometer, is sensitive to atmospheric pressure.
An altimeter does not actually measure altitude directly, but rather just atmospheric pressure. So an altimeter is actually a barometer created for a specific purpose. See related link The altimeter measures the height above the ground and has a pointer which is adjustable depending in which air field you are taking off on. it measures the pressure of the air as you get higher off the ground the pressure reduces therefore it is able to… Read More
an aneroid barometer
It was not used as a barometer.
The main difference between altimeter and cabin altimeter is the place where they take their pressure: Altimeter takes the pressure from static ports, while cabin altimeter takes it's pressure from the cabin.
A barometer is an instrument used to measure atmospheric pressure. A circle does not have a barometer!
A barometer is used to measure air pressure
An altimeter is an instrument which measures altitude. The standard altimeter measures altitude above sea level. The radar altimeter, however, measures altitude above ground level.

The barometer is used to measure atmospheric pressure.

An altimeter is a piece of apparatus which measures someone's altitude.

When Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates?
true altitude at field elevation.

No, a barometer measures pressure.
The most commonly used barometer is the mercury barometer.However, it is not easy to transport but it gives more accurate results. Another type of barometer is Aneroid barometer which is easy to transport and handle.
My GPS instrument contains a barometric altimeter.
My handheld GPS instrument has a barometric altimeter in it also.

An altimeter is an altitude measuring device (alti + meter).
My wristwatch has an altimeter, which as a backpacker, I find very useful.
I want to see your 4runner if it has an altimeter in it! If so, what is the max altitude you can fly to? Did they really put an altimeter in 4 runners??
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.
my American friend Keith Giles has one which includes an altimeter
Altimeter 2992 means that the air pressure is 29.92 in. HG. 29.92 in. HG. With this information, you would calibrate your altimeter to 29.92.
a barometer measures air pressure
Mercury barometer is used for measuring atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude.
Because the absolute air pressure decreases as you go up in elevation. This is because the height of the air column above you is shorter. Since the aneroid barometer is a pressure measuring instrument, its reading will decrease as you move upward in elevation. Put another way, the barometric pressure decreases with elevation. More: Because the air pressure decreases as you go up in elevation. If we know the correction factor to adjust for sea… Read More
notes about pulsed Doppler radar FM altimeter
Altimeter indicates altitude of air craft from ground. they are known as radio altimeters.
an altimeter is an aircraft instrument that measures the altitude/elevation above ground level.
I wanted to know what the pressure in the air was so I used a barometer!!!!
mercury barometer and a aneroid barometer
Barometer is used to measure atmospheric pressure. Hydrometer is used to measure specific gravity.
A barometer is a device used to measure atmospheric pressure. If pressure is high (good weather), then pressure on the barometer will exceed 1000 millibars. If the pressure is low (bad weather), then the pressure reading on the barometer will be below 1000 millibars.
