Pressure gauges are instruments that measure pressure using gauge pressure. These instruments are functionally similar with manometers but generic pressure gauges do not use columns of water with their measurements. Regardless, the principle behind the two types of instruments are largely the same.
The pressure measured using pressure gauges is called gauge pressure since manometers measure pressure by comparing the pressure inside a vessel or container with atmospheric temperature. This is different from instruments that use absolute pressure as their pressure mode which doesn’t use atmospheric pressure as a reference point. A vessel that gives a ‘zero’ rating when measured with a manometer means that the pressure inside it is equal to atmospheric pressure and not actually devoid of any pressure at all.
