The manometer is so often used to measure pressure that the difference in column heights is also a common unit. This is expressed in inches or centimeters of water or mercury at a specific temperature, which can be changed to standard units of pressure with a conversion table.
What Is a Manometer Used to Measure?
A manometer is a device that is used to measure the pressure of a fluid. It is typically used to measure the pressure of a gas or a liquid.
There are two types of manometers: the aneroid manometer and the liquid–filled manometer. The aneroid manometer is the most common type of manometer.
It consists of a metal chamber that is filled with a gas, such as air. The chamber is connected to a pointer that indicates the pressure of the gas on a scale.
The liquid–filled manometer is less common than the aneroid manometer. It consists of a glass tube that is filled with a liquid, such as mercury.
The tube is connected to a pointer that indicates the pressure of the liquid on a scale. Both types of manometers are used to measure the pressure of a fluid.
However, the aneroid manometer is more common because it is easier to use and more accurate.
