How do manometers work?

I - Most pressure gauges, or manometers, measure the difference between the pressure of a fluid and the local atmospheric pressure.
II - For small pressure differences, a manometer consisting of a U-shaped tube with one end connected to the container containing the fluid and the other end open to the atmosphere is used.
III - The tube contains a liquid, such as water, oil or mercury, and the difference between the levels of the liquid in both branches indicates the difference between the pressure of the container and the local atmospheric pressure.
IV - For larger pressure differences, the Bourdon gauge is used.

Manometers work by measuring the pressure difference between a fluid and the local atmospheric pressure. There are different types of manometers, but for small pressure differences, a common design is a U-shaped tube. One end of the tube is connected to the container containing the fluid, while the other end is open to the atmosphere. The tube is filled with a liquid, such as water, oil, or mercury. The difference in the levels of the liquid in both branches of the tube indicates the difference in pressure between the container and the local atmospheric pressure. For larger pressure differences, a Bourdon gauge is typically used.
