An anemometer is a tool used to measure the speed of the wind. The instrument derives its name from the Greek word "anemos" which means wind. There are four types of anemometers:
a) Vane-style of anemometer
b) Helicoid propeller anemometer
c) Hand-held low-speed vane anemometer, and;
d) Portable digital anemometers.
Anemometers are widely used in air velocity testing and quality measurement purposes. Cup anemometers have a microprocessor circuit that accounts for reading accuracy. These anemometers are water-resistant and operate on DC 1.5V (UM4/AAA) x 4 PCs batteries. Digital anemometers are professional testing tools used to measure dew point temperature, wind speed, and air volume. These anemometers are compact and ergonomically designed. Digital anemometers have an LCD screen with backlight for easy reading of testing results.
Anemometers are designed to measure:
A) Air Velocity in meter/seconds, feet/seconds, feet/minutes, Km/hour, mile/hour, knots
B) Air Flow is measured in cubic feet/minutes (CFM), cubic meter/minutes (CMM), cubic meter/seconds (CMS).
