Manometer

A manometer is a device used to measure pressure, typically of gases or liquids. It often consists of a U-shaped tube filled with a liquid, such as mercury or water. When one side is connected to a container or system, any pressure difference causes the liquid to move, indicating the pressure level. The height difference of the liquid columns corresponds to the pressure exerted. Manometers are precise tools commonly used in labs, industry, and HVAC systems to ensure that pressure levels are within safe and functional ranges.
