To determine pressure
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.

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.
You can use a manometer.
Manometer
A double tube manometer measure pressure. Manometers use liquid in a column and balance it against the pressure that they are measuring.
