A manometer is a pressure gauge, "Manometer" reads extremely low pressures that are very close to atmospheric pressures, "pressure gauges" read much larger pressures.
A magnehelic gauge is a specific type of pressure gauge that uses a diaphragm to measure pressure differentials, displaying the pressure on a dial using a needle. A manometer is a more general term for any device that measures pressure, typically using a column of liquid to indicate pressure levels. Manometers can come in various forms, such as U-tube and well-type manometers.
To determine the gas pressure in a closed container, you can use a pressure gauge or a manometer. These devices measure the force exerted by the gas molecules on the walls of the container, which is directly related to the gas pressure. By using the readings from the pressure gauge or manometer, you can calculate the gas pressure in the closed container.
Absolute pressure is measured relative to a perfect vacuum, while gauge pressure is measured relative to atmospheric pressure.
Gauge pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the pressure measured relative to a perfect vacuum.
Absolute pressure is the total pressure exerted by a fluid, including atmospheric pressure. Gauge pressure is the pressure measured above atmospheric pressure.
A manometer is a pressure gauge. A micro manometer is either a really small pressure gauge, or a pressure gauge used to measure really small pressure difference.
A pressure gauge or manometer is typically used to measure pressure above atmospheric pressure. These devices can accurately measure the pressure difference between the system being measured and atmospheric pressure.
A micro manometer is a device used to measure very low pressures with high accuracy. It is typically used in applications where precise pressure readings are required, such as in research laboratories or clean room environments. The measurements obtained from a micro manometer can help ensure the proper functioning of systems that rely on precise pressure control.

Bourdon gauge
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
A "U" shaped manometer is used to measure differences in pressure between the two ends. If one end is open to the atmosphere, it measures the difference between atmospheric pressure and the pressure where the other end is connected. When one end is evacuated and sealed it measures the difference between the vapor pressure of the manometer fluid (which is usually negligible) and the pressure of whatever the other end is connected to. When connected to two different locations along a pipe, it measures the pressure drop. If a constriction is placed in the pipe, this can be used to gauge the flow rate in the pipe.
differential pressure gauge.
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 instrument used for measuring pressure is called a manometer.
