Noun
An instrument for measuring the tension or elastic force of gases, steam, etc., constructed usually on the principle of allowing the gas to exert its elastic force in raising a column of mercury in an open tube, or in compressing a portion of air or other gas in a closed tube with mercury or other liquid intervening, or in bending a metallic or other spring so as to set in motion an index; a pressure gauge. See Pressure, and Illust. of Air pump.

C." or the words "water column" are often printed on gauges and measurements that use water for the manometer. Source: Internet
Hydrostatic Hydrostatic gauges (such as the mercury column manometer) compare pressure to the hydrostatic force per unit area at the base of a column of fluid. Source: Internet
If the wind blows into the mouth of a tube it causes an increase of pressure on one side of the manometer. Source: Internet
Liquid column main The difference in fluid height in a liquid column manometer is proportional to the pressure difference. Source: Internet
