A diffrntial u tube manometer is a long bent tube whos both ends r conctd at points in a pipe where presure is to b measurd.Take d reading in d first tube h1 in mm n do similarly in secnd tube n its h2. Den d differential head wil b h1-h2.

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 are the advantages of a u-tube manometer than a piezometer
A double tube manometer measure pressure. Manometers use liquid in a column and balance it against the pressure that they are measuring.
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.
differential pressure gauge.
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.

Inverted U-tube manometer is used for measuring pressure differences in liquids. The space above the liquid in the manometer is filled with air which can be admitted or expelled through the tap on the top, in order to adjust the level of the liquid in the manometer.
One of ends of the tube is used for pressure measurements, the other can be left open to the atmosphere to measure static pressure, or can be attached to the low end of a pressure system to measure differential pressure.
It is defined as the instrument which can measure the difference between 2 pressure i.e high & low
what are the advantages of a u-tube manometer than a piezometer
the most common type of manometer are u-tube type,inclined and the cistern type of manometer
