A manometer is used to measure pressure. A well-type manometer measures a singular height of pressure and is normally highly accurate.
the most common type of manometer are u-tube type,inclined and the cistern type of manometer
What is a two liquid well type manometer is one of the three main types of manometers. This type is best applied to reading scales that are properly calibrated and in the right units.
A manometer measures pressure. The units depend on the type of manometer and how it's calibrated. Units include psi, barr, Torr, atm, pascals, and kilopascals.

A manometer is an instrument for measuring the pressure acting on a column of fluid. The main types of manometers are U-tube, well type, and inclined.
Compound Manometer is an 'U' Tube manometer having 'T' joints at appropriate equal elevation in the columns of U tube manometer where the impulse lines are to be connected to measure Differential Pressure. T joint allows the use Two liquids simultaneously in the manometer. i.e. the liquid who's differential pressure is to be measured being lighter it will gauge at the top and a heavier liquid which does not dissolve with the lighter fluid will gauge at the bottom. Elevation difference in lighter liquid as well as heavier liquids gives their respective differential pressure. Both the differential pressure will be equal in terms of Pressure Units. Since two liquids are used simultaneously this type of U tube manometer is called Compound Manometer.

by setting up a manometer
It is a type of manometer, an object used to measure the pressure of different things, and the open armed manometer allows for the atmospheric pressure in the tube of the manometer. So the sample gas pressure pushes on the mercury that is already being pushed on by the atmospheric pressure. Then you add the atmospheric pressure to the change in the mercury (in mm) and that gives you your pressure. It's like a tire gauge.
The manometer becomes much more sensitive ( 13.59 times more sensitive than a mercury manometer)
