Function

Instrument used to measure small changes in atmospheric pressure (+/- 10 cm of hg) in physics experiments.

Technical

Liquid column gauges consist of a vertical column of liquid in a tube whose ends are exposed to different pressures. The column will rise or fall until its weight is in equilibrium with the pressure differential between the two ends of the tube. The difference in liquid level represents the applied pressure. The concept of the manometer is now used in aviation instruments and weather forecasting, etc.
