Simple Method for Reading an Air Velocity Meter

Air velocity meters are easy to read using a few simple tips.

Air velocity meters, or anemometers, are used to measure air velocity and air pressure. Many models are available, from hand-held meters for taking quick measurements to larger devices for logging more precise results. However, most meters have straightforward displays and can be read using a few basic tips.

Units

Check what units your meter uses. Wind velocity is most commonly measured in miles per hour, kilometers per hour or nautical knots. Consult a conversion table to see how these measurements can be correlated to weather conditions.

Range

Make sure the device you use is appropriate for the range of air velocity you are measuring. For instance, a meter designed to measure nautical wind speeds may not be a good choice for measuring household ventilation.

Conditions

When taking measurements, hold your meter in a place where the air or wind can be felt steadily. If the wind is stopping and starting in brief gusts, or if the meter is not kept stable during use, you may receive conflicting or inaccurate results.
