Manometers
The manometer is the simplest measuring instrument used for gauge pressure (low-range pressure) measurements, by balancing the pressure against the weight of a column of liquid. The action of all manometers depends on the effect of pressure exerted by a fluid at a depth.
There different types of manometer:
U-tube Manometer
The U-tube is the simplest form of manometer and is used for experimental work in laboratories. By suitable choice of liquids, a wide range of pressure can be recorded.
Construction Manometer
It consists of a transparent (glass) tube constructed in the form of an elongated U and is partially filled with a liquid, most commonly water or mercury. Water and mercury are used because their specific weights for various temperatures are known exactly and they do not stick to the tube. One ned of the tube is connected to one pressure tap and the other end is connected to the other pressure tap, or it may be left open to the atmosphere.
Working Manometer
When there is a pressure difference between the two ends of the tube, the liquid level goes down on one side of the tube and up on the other side. The difference in liquid levels from one side to the other indicates the difference in pressure.
Hopes that this helps!! ^_^!!

Manometer is a device used to measure pressure.It is a U shape transparent pipe filled with liquid (usually water) which density is known.One side of the tube is connected to pressure under test and the other side is left open to atmosphere.Before any pressure applied the level in manometer is same. When the pressure is applied the level of manometer will change and it is equivalent to applied pressure in millimetre or inches of the liquid column.Usually there are scales marked on the tube.
Hope this will help

A manometer is a pressure guage, and there are many types to measure gases and liquids. One type of manometer is a barometer used to measure air pressure and forecast weather.

Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges
A manometer is a pressure measuring instrument, usually limited to measuring pressures lower than atmospheric. It is often used to refer specifically to liquid column hydrostatic instruments.
A vacuum gauge is used to measure the pressure in a vacuum, which is broadly divided into two categories: high and low vacuum (and sometimes ultra-high vacuum). Many of the different techniques used to measure these categories have an overlap at some point in the pressure range. By combining several different types of gauge it is possible measure system pressure from 10 mbar down to 10e-11 mbar
