Difference between Barometer and Manometer

Difference between Barometer and Manometer
What is Barometer?
A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems and frontal boundaries.
What is Manometer?
Manometers are devices in which columns of a suitable liquid are used to measure the difference in pressure between two points or between a certain point and the atmosphere.
Barometer vs Manometer
Barometer and manometer are used to measure pressures. They are simple instruments, which are based on the same principle. However, the occasions where they are being used are different. Today, there are many sophisticated equipments to replace the old barometers and manometers, and they are more user friendly, fast and reliable.
What is the difference between Barometer and Manometer?
1.Barometer is a type of close-end manometer.
2.Barometer is specially designed to measure the atmospheric pressure, whereas manometer can also be used to measure the pressures, which are lower than atmospheric pressure.
3.In a manometer, both ends of the tube are open to outside (some may have a one closed end), whereas in the barometer one end of the glass tube is sealed and it contains a vacuum.
4.A barometer is an instrument to measure the environment pressure - the range is very limited to about 5%.
5.A manometer is a standard pressure instrument, built for any defined measuring range, possibly up to 100 bar or more.
