The schematic design of a mercury barometer contains a simple mercury filled reservoir having an inverted glass tube (around 3 feet in length) in it. The cup anemometer consists of a vertical pole with four horizontal arms attached to the top. When the wind is blowing, the wind vane points into the wind. A wind vane measures wind direction. Does Matthew Gray Gubler do a voice in the Disney movie Tangled? Portable handheld anemometers are in form of digital anemometers. Wind has both speed and direction. air pressure. Aneroid barometer and mercury barometer are two such barometers. With a cross that has the letters N (north), E (east), S (south), W (west). Earliest thermometers used water instead of mercury, but as water freezes at zero degrees Celsius, the thermometer failed to measure temperatures below this temperature. Anemo (Greek word) means wind and as a name advocates , Anemometer is popularly known to measure the flow rate of fluids , compressible as well as incompressible (GAS or Liquid) . An Italian scientist named Torricelli built the first barometer in 1643.

This much is perhaps known to all of us, but most of us would draw a blank if asked to explain the differences in a barometer and a thermometer. Olivia is a Graduate in Electronic Engineering with HR, Training & Development background and has over 15 years of field experience. The barometer is used for measuring air pressure, but its use is more frequent in areas such as meteorology, for weather forecasting more precisely. Key differences . Thermometers in US measure temperature in Fahrenheit but the scale used in the rest of the world is Celsius. Barometers and pressure altimeters (the most basic and common type of altimeter) are essentially the same instrument, but used for different purposes. Most widely used for wind-speed measurements is the revolving-cup electric anemometer, in which the revolving cups drive an electric generator. When this tube is placed in the reservoir, the mercury level goes down, creating vacuum at the top. The air pressure at the center of a storm is low compared to areas around the storm. Toricelli invented the first barometer (using mercury) in 1643 which is the technique still being used today. You will now have a good understanding of what an anemometer is, what it is used for, and how the different types of anemometers work. Is Mike Tyson any relation to Cicely Tyson?

The difference between anemometer and high temperature anemometer. This horizontal member features equal weight on both sides of the vertical rod, but one side is much larger so that it will catch the wind. A hygrometer measures There is a red or silver colored line calibrated on this tube and it moves up or down depending upon the temperature. An altimeter is intended to be used at different levels matching the corresponding atmospheric pressure to the altitude , while a barometer is kept at the same level and measures subtle pressure changes caused by weather and elements of weather. They are by no means the only anemometers in existence, though. When the atmospheric pressure goes up, mercury level in the tube rises, and when atmospheric pressure goes down, so does the level of mercury. Actually, anemometers can be categorized into two categories such as portable handheld anemometers and those affixed to the ground at weather stations. Other anemometers calculate wind speed in different ways. The tube is closed at the top and is already filled with mercury. The difference between the two devices: There are three main points in which the two devices differ: Although the barometer is a little simpler than the manometer, it's actually a close-end manometer; You can't measure other types of pressure with a barometer, except for air pressure.
