For a very basic explanation, a manometer measures the pressure differential between a closed pressure applied at one end and an open pressure at the other.
For example. If you have a typical u-bend manometer and you apply an air pressure at one end, the liquid will raise correspondingly, as the pressure on the closed side increases more and more above the ambient air pressure.
The amount it rises depends on the density of the liquid used and the diameter of the tubing.
So basically a manometer uses the height of a liquid to translate the amount above ambient air pressure, which is considered zero, of your pressure source.

What are the advantages of U tube manometer than a piezometer?
what are the advantages of a u-tube manometer than a piezometer
What does a double tube manometer measure?
A double tube manometer measure pressure. Manometers use liquid in a column and balance it against the pressure that they are measuring.
How do you calculate static pressure of AHU?
by u tube manometer
What is compound manometer?
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.
What is the difference between a manometer and a pitot?
A manometer is a device for measuring pressures, especially the word is used for pressure meters that are constructed to use a liquid in a transparent U-tube. A peizometer is specifically about measuring pressures in ground water wells.
Types of manometer?
the most common type of manometer are u-tube type,inclined and the cistern type of manometer
What are the advantages and disadvantages for inclined tube manometer?
the scale that is attached to the inclined tube are more sensibly then scale in vertical form that are in U-tube manometerdisadvantage is that it is costly and tough to handle.
Inclined-tube manometer why are they used to measure low pressure?
the fluid level in manometer will rise through an inclined line rather than vertical line. So when ever there is slight variation in pressure the manometer (inclined) will be able read it. The pressure drop is given by P=h*density*g*sin(angle).
How manometer can read a very small changes in pressur?
By cathetometer (precise but expensive), or by inclined tube method
What are the advantages of U tube manometer than a piezometer?

What are some types of manometers?
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.
What is Working principle of venturi tube?
Venturi tube is used to for flow measurement. It work on the principle of Bernoulli Equation.
How do you use YouTube manometer?
I think you're looking for U-Tube Manometer
What are the uses of the manometer?
air, fluids and very low pressures equal & unequal leg u tube manometer, cistern manometer, u tube manometer.
What does a double tube manometer measure?
A double tube manometer measure pressure. Manometers use liquid in a column and balance it against the pressure that they are measuring.
What is the definition of U-tube manometer?
The U-tube manometer is a simple instrument used to measure differences of pressure. Search the link below for details.
Why U-tube is inverted in inverted differential manometer?
when the fluid is flowing on the pipe which is lying on the ground then we cannot install ordinary manometer to measure the pressure, that's why we use inverted u tube manometer in such case.
