An anemometer is a device used to measure the velocity or speed of air (gases) in both confined and unconfined flows, such as atmospheric wind and airflow in ducts.By detecting the pressure that is created by the movement of the air, air velocity is determined. Air density and velocity are also correlated, with the assumed constants being 70°F and 29.92 in Hg. Capacitive pressure sensors and hot-wire anemometers are the two most popular methods for measuring velocity.
Air velocity Meter
1. A Hot Wire Anemometer
A hot wire anemometer measures the heat loss from a wire that has been electrically heated and placed in the air stream to determine the velocity and direction of a fluid (in this case, air).
2. Velometer Airflow Measure Probe
Using a velometer is another way to gauge airflow velocity. A velometer gives a quick reading of the air speed at a particular location where the probe is placed.
3. Airflow testing
A component or product’s ability to move air through, into, or out of it can be measured using an airflow test, as can the performance characteristics of an air-moving equipment like a fan or blower.
4. Laminar air flow level
Laminar in this context refers to air flowing continuously in one direction with little or no turbulence. The air flow velocity stays within the range of 0.3 and 0.5 m/s. Such workstations are used in laboratories to provide a particle and bacterium-free working environment for performing specialised tasks.
