उत्तर
An altimeter is a device used in aircraft to measure its altitude.
Principle: Atmospheric pressure decreases with the increase in height above the sea level; therefore, a barometer measuring the atmospheric pressure can be used to determine the altitude of a place above the sea level.
The scale of altimeter is graduated with height increasing towards left because the atmospheric pressure decreases with increase of height above the sea level.
