   How accurate is an anemometer?

   • Accuracy is an important quality of an anemometer. A high-quality device will provide a wind speed reading accurate to approximately ±0.5 m/s (±2km/h or ±1mph). It’s important to remember that environmental wind speed isn’t constant, as it’s changing all the time.

   Does a cup anemometer measure wind?

   • A cup anemometer has to be held vertically, and it will measure wind from any direction. There are other types – ranging from a simple “ping-pong ball” anemometer you can make yourself to more accurate but more expensive sonic anemometers that rely on measuring the speed that sound travels in the wind.

   How do Ultrasonic anemometers measure wind speed?

   • Ultrasonic anemometers measure wind speed. They do this by sending a sound pulse back and forth from a transmitter to a receiver over a span of a few inches to calculate the speed of the wind blowing in between the two sensors.

   How accurate is a wind speed reading?

   • A good anemometer will give you a wind speed reading accurate to about ±0.5 m/s (±2km/h or ±1mph), but that's often far more accurate than you need. Remember that the wind speed isn't constant—it's varying all the time!

   How accurate is a wind speed meter?

   • With brilliantly accurate scientific instruments, you can make measurements that have no real meaning or value if you don't think carefully about what you're doing. A good anemometer will give you a wind speed reading accurate to about ±0.5 m/s (±2km/h or ±1mph), but that's often far more accurate than you need.

   • Measuring Gusts and Wind Intensity

   Wind speed is normally measured by a cup anemometer consisting of three or four cups, conical or hemispherical in shape, mounted symmetrically about a vertical spindle. The wind blowing into the cups causes the spindle to rotate. In standard instruments the design of the cups is such that the rate of rotation is proportional to the speed of the win...

   Where wind measurements are made in extreme weather conditions, such as on the top of mountains, a heated sonic anemometer is used having no moving parts. The instrument measures the speed of acoustic signals transmitted between two transducers located at the end of thin arms. Measurements from two pairs of transducers can be combined to yield an e...

   Because wind is an element that varies rapidly over very short periods of time it is sampled at high frequency (every 0.25 sec) to capture the intensity of gusts, or short-lived peaks in speed, which inflict greatest damage in storms. The gust speed and direction are defined by the maximum three second average wind speed occurring in any period. A ...

   How accurate is an anemometer? Different anemometers will have different levels of accuracy. Generally speaking the more expensive the unit the more accurate you can expect it to be (no surprise there!). A common handheld decent quality anemometer accuracy range is within ±3%.

   • Mechanical anemometers. Some of the simplest anemometers work in exactly this way. They're little more than an electricity generator mounted in a sealed-up metal cylinder with an axle protruding upward from it.
   • Ultrasonic anemometers. You probably know that sound travels by making air molecules move back and forth. It's fairly obvious that the speed of the wind affects the speed at which sounds travels.
   • Laser interferometer anemometers. You can make a similar—but much more precise—measurement using beams of light instead of ultrasound. The basic principle is called interferometry, and it can be used to measure all kinds of different things with incredible precision.
   • Doppler laser anemometers. Given its high-precision nature, you'd use a laser interferometer for making very precise measurements in a laboratory. But some laser anemometers are robust enough for more general use outdoors.

   Mar 6, 2014 · A cheaper type is the propeller anemometer, but to get an accurate measure of speed, it has to be kept facing the wind – whose direction changes from one moment to the next, which can sometimes be tricky. A cup anemometer has to be held vertically, and it will measure wind from any direction.

   The resulting elevation difference in the two legs of the U tube is an indication of the wind speed. However, an accurate measurement requires that the wind speed be directly into the open end of the tube; small departures from the true direction of the wind causes large variations in the reading.
