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.
A manometer's sensitivity can be increased by increasing the height differential between the two limbs of the manometer, using a liquid with low density, and increasing the diameter of the manometer tube. These factors can help increase the deflection of the liquid in response to pressure changes, improving sensitivity.
Mercury is a dense and toxic liquid metal that can be hazardous to handle. Using mercury in an inverted U-tube manometer may pose a safety risk due to the potential for spills or leaks. Additionally, mercury is a costly material compared to other less toxic and easy-to-use liquids such as water or oil.
To set up a manometer, first ensure that it is securely mounted in a vertical position. Fill the manometer with a fluid, typically mercury or water, making sure there are no air bubbles. Connect the manometer to the system you want to measure the pressure of, and then observe the height difference of the fluid levels in the manometer to determine the pressure.
Manometer.
The term "manometer" is derived from the Greek word "manos," meaning thin, and "metron," meaning measure. The device measures the pressure of a gas by balancing it with a liquid column, which is indicated by the height difference between the two.
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.

When mercury is used a manometer fluid and the manometer tube is inverted it will measure the small pressure difference in liquids. This is a tool used by scientists.

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.

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. Equating the pressure at the level XX'(pressure at the same level in a continuous body of static fluid is equal), For the left hand side: Px = P1 - rg(h+a) For the right hand side: Px' = P2 - (rga + rmgh) Since Px = Px' P1 - rg(h+a) = P2 - (rga + rmgh) P1 - P2 = (r - rm)gh If the manometric fluid is choosen in such a way that rm << r then, P1 - P2 = rgh. For inverted U - tube manometer the manometric fluid is usually air.

It is defined as the instrument which can measure the difference between 2 pressure i.e high & low
In the inverted region of Marcus, unique characteristics or phenomena such as negative differential resistance and negative differential capacitance can be observed. These phenomena involve the decrease in current or capacitance with increasing voltage, which is opposite to the typical behavior in electronic devices.

A manometer is attached to a laminar air flow unit to measure and maintain the proper air pressure differential inside the unit. This helps ensure that contaminants are not introduced into the clean airflow, maintaining the sterile environment needed for tasks such as laboratory experiments or pharmaceutical production.
