A manometer or pressure gauge is an instrument for recording and displaying the physical pressure of a medium (liquid, gas).
In most applications, relative pressure is measured – that is, relative to atmospheric air pressure.
In contrast, absolute pressure measuring instruments (e.g. barometers) use a vacuum as the reference pressure.
