When are air velocity measurement used
An instrument that measures air pressure is called a barometer. It is typically used to predict changes in weather patterns based on fluctuations in air pressure.
A barometer is the tool used for measuring air pressure. It can be either an aneroid or mercury barometer.
The velocity pressure can be used to calculate the velocity of air in the duct using the formula: velocity = √(2 * pressure / air density). Assuming standard air density and converting 0.20 in w.g. to the appropriate pressure unit, the velocity of air in the duct would be approximately 903 ft/min.
A velocity microphone is a sensor whose electric output depends on the velocity of the air particles that form a sound wave . Examples are a hot-wire microphone and a ribbon microphone (bi-directional).Velocity-sensitive microphones also respond much more to wind noise than pressure sensitive microphones (omnis). You get heavy bass tip-up or proximity effect if the sound source is close to the microphone. Cheers ebs
The speed of an airplane is measured by a system known as the pitot-static system which compares the difference between the static air pressure that exists around the aircraft and the dynamic, or ram air pressure which is a function of the speed the aircraft is moving through the air. The devices used to gather this information are the static air port (which measures static air pressure) and the pitot tube (which measures ram air pressure). This differential is displayed on an instrument in the cockpit called an airspeed indicator (or ASI).
An instrument for measuring atmospheric pressure, used especially in weather forecasting.
An easily portable instrument used for measuring air pressure is called anedroid barometer.

A barometer measures air pressure; a hygrometermeasures humidity, or the moisture content of the air; and an air sampler (or high volume air sampler) is used to measure the purity or pollution level of the air.
Anemometers measure air velocity. The spinning cups of a weather station are a typical application.Air velocity can also be measured using a pitot tube connected to a gauge that measures pressure. That is the basis for an airplane's air speed indicator.Air velocity can also be measured using a pressure gauge at a venturi. The faster a fluid moves through a venturi, the lower its pressure. It may sound strange but, air is considered to be a fluid.A hot wire is cooled by moving air. If you know the temperature of the wire you can relate the temperature to the air velocity and thereby know how fast the air is moving in a duct. This sort of device is known as a "Hot wire anemometer". For a picture, search for "TSI Velocicalc".A baseball pitcher may drop a handful of dirt or grass to gauge the velocity and direction of the wind. A wind sock serves a similar purpose. Neither of these methods gives a numerical value but, can allow a person to compare the wind to previously observed conditions.
-meter is the suffix used in names of measuring instruments. Specifically, a barometer is used to measure air pressure.
Its important for the pilots in air planes and the designers of air planes. Please recommend me!
You would use a Spirometer.
Humidity can be directly measured by forced condensation either by pressurized or reduce the temperature and measure the water content directly. Alternative to direct measurement, humidity can be measure using air electro-conductivity since presence of water would increase the conductivity so it could interpret the conductivity to water content.

The instrument used to measure elevation is called an altimeter. It works by measuring air pressure changes as altitude changes, providing a rough estimate of elevation above sea level.
