Question

Difference between manometer and barometer.

Answer 1

Barometer	Manometer
A barometer is a device that measures changes in air pressure as a function of distance above or below sea level.	A manometer is a device that measures liquid pressure in relation to an external source, which is commonly the earth's atmosphere.
It was invented in 1643.	It was invented in 1661
It was invented by Evangelista Torricelli.	It was invented by Otto von Guericke.
It's used to measure atmospheric pressure, weather forecasting, in scuba diving to keep track of the diver's air tank, in smartphone fitness apps, and in the GPS chip of smartphones to get faster locks and delivery of altitude data.	It's used to measure smaller or bigger pressure variations, monitor gas pressure in water pipelines, and measure water pressure, among other things. Mercury Absolute manometers are utilized in power plants and research laboratories for a variety of applications. utilized weather
Water barometers, Mercury barometers, Fitzroy barometers, Fortin barometers, Sympiesometers, Wheel barometers, Vacuum Pump Oil barometers, Aneroid barometers, and MEMS barometers are examples of sub-types of barometers.	U-tube manometers, Differential U-tube manometers, Inverted U-tube manometers, Micro manometers, Inclined manometers, Ring-Balance manometers, Digital manometers, and Analog manometers are examples of sub-types of manometers.
High density, low vapor pressure, moderate evaporation rate, and high density are all advantages of barometers	Manometers have the following benefits: less maintenance, lower costs, easy manufacture, and excellent accuracy and sensitivity.
Some barometers are easy to move, while others are not, posing a high risk of liquid contamination is a big disadvantage of barometers.	Manometers have the following drawbacks: they are large and unwieldy. Leveling is required, condensation creates inaccuracies, and dynamic performance is poor.
