It is defined as the instrument which can measure the difference between 2 pressure i.e high & low
differential pressure gauge.
The U-tube in an inverted differential manometer is inverted because it allows the device to measure pressure differences accurately. When one side of the U-tube is connected to a system with higher pressure than the other side, the liquid in the U-tube moves to create a visible difference that can be measured. If the U-tube were not inverted, the liquid would not move, and accurate pressure readings could not be obtained.
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.
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.
what are the advantages of a u-tube manometer than a piezometer
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.
A U-tube manometer is a device used to measure pressure differences in a system. It consists of a U-shaped tube partially filled with a liquid, such as mercury or water, and is connected to the system where pressure needs to be measured. The height difference of the liquid levels in the two arms of the U-tube indicates the pressure difference.
A U-tube manometer is used to measure pressure by comparing the height difference of the liquid levels in two arms of a U-shaped tube. It is commonly used in various applications, such as in fluid mechanics experiments, HVAC systems, and pressure monitoring in chemical processes.
