A manometer operates on the principle that pressure changes on a liquid will cause it to rise or fall in a transparent tube The principle behind a manometer gas or liquid pressure gauge is extremely simple This liquid movement reflects the difference between the applied unknown pressure.

A manometer works on a very simple and natural principle of fluid behavior called hydrostatic equilibrium
This principle explains how liquids behave.
The discussion centers on solving a fluid mechanics problem involving a manometer containing two liquids, specifically analyzing pressure differences and densities.
