![]() That Plate Anemometer, doesn’t have a spring on it, there’s no spring mechanism on the thing! It’s not good in low wind speeds but is good in strong wind! Its also handheld, and it doesn’t pivot rapidly, I did that so the resonance wouldn’t mess up the reading! The plate will last indefinitely, and it never needs re-calibration.

Anemometer types portable#These portable devices are accurate measures for wind speed anywhere you go. “What tool measures wind speed the best?” In our opinion, it comes down to cup anemometers for personal weather stations and handheld anemometers. Others can be pretty costly and may involve unwieldy contraptions. Keep in mind that some methods may not be very reliable. It also requires a lot of technical expertise to operate.Ĭlearly, there’s a lot of ways you can use to measure wind speed. This instrument to measure wind speed is extremely accurate as well as very expensive. The receiving station compares this reflected light to the reference beam to calculate the speed of the moving air. Laser light bouncing off air particles headed away from the detector undergo red shifting to a lower frequency. If the air is rushing towards the measuring beam, the light waves reflecting off it are squeezed into a higher frequency. One portion is used for reference while the other is aimed at the wind. ![]() ![]() The difference is that laser light is what measures wind speed. This system relies on the same principals as an ultrasonic anemometer. ![]()
