The Dwyer 480 Vaneometer anemometer with swing vane indicator measures air velocity from 25 to 400 fpm, and has a built-in spirit level vial to maintain horizontal plane for accurate readings. The meter has ABS (acrylonitrile butadiene styrene) housing that resists impacts. It is sized for portability and includes a mounting bracket for continuous monitoring applications. The scale can be read from both sides of the meter. This anemometer is used for monitoring ventilation in spray booths and exhaust hoods, among other low-velocity applications.

Anemometers, also called wind meters, measure air velocity and are most commonly used for weather monitoring to determine wind speed and for HVAC applications to determine air flow within ducts. In addition to air velocity, anemometers may measure wind direction, air pressure, air flow volume, air temperature, humidity, light, and other properties. The most common types of anemometer are cup, vane, hot-wire, and Pitot tube. Cup and vane anemometers calculate air velocity based on the number of rotations of the cups or vane. Hot-wire anemometers calculate air velocity by measuring the change in electrical resistance as air flow cools a heated wire. Pitot tube anemometers measure air pressure within a tube and calculate air velocity based on the difference in pressure between the air inside and outside of the tube. Many anemometers have digital readouts and can display air velocity readings in different units of measure, such as meters per second (m/s), feet per minute (ft./min. or fpm), knots, miles per hour (mph), and kilometers per hour (km/h).
