👉 A manometer is a device used to measure the pressure in an area by observing how much water flows through a narrow tube. It works by measuring the ratio of the cross-sectional area of the tube and the depth at which water flows. The measurement can be made in various units, such as inches per unit of length, or using meters per unit of volume. Manometers are commonly used in scientific research to measure atmospheric pressure and other pressures in various environments.
