A manometer is a precision instrument used to measure pressure, which is the force exerted by a gas or liquid per unit surface area owing to the effects of the weight of that gas or liquid from gravity. Depending on the type and how they are configured, manometers can be set up to provide a measurement of different pressure values. There are different types of manometers, including:
-
U-Tube Manometer: This type of manometer features a vertical or inclined U-tube column that is filled with a reference liquid, such as mercury, to display the pressure level. When the columns of the device are exposed to the atmosphere, the levels of liquid in the limbs are equal, indicating atmospheric pressure. When one of the columns is connected to the pressure vessel, there will be a difference in the level of the liquid in the limbs, which signifies the pressure of the liquid in the vessel.
-
Enlarged-Leg Manometer: This type of manometer is similar to the U-tube manometer, but one of the legs is enlarged to increase the sensitivity of the device.
-
Well-Type Manometer: This type of manometer is like the U-tube style, but one of the legs of the U has a cross-sectional area that is larger than the other leg. This design allows for greater sensitivity and accuracy.
-
Inclined-Tube Manometer: This type of manometer features a tube that is inclined at an angle to the horizontal. The pressure difference between the two ends of the tube is proportional to the difference in height of the liquid in the tube.
Manometers are commonly used in various fields, including medicine, engineering, and physics, to measure pressure in different applications.
