2 instruments for measuring wind speed and direction

In meteorology, wind speed and direction are important reference data and have many uses. For example, in sports events, it is necessary to measure wind speed and direction.

In regular sporting events, the results of the game are accurate to one-hundredth of a second, and this seemingly small unit is affected by the wind. According to research, in a 100-meter running race, air resistance can make a difference of 0.16 seconds. This will affect the fairness of the game. Therefore, the regulations of the regular track and field competition are: the distance of 200 meters and less than 200 meters, as well as the long jump, triple jump and other projects, where the average wind speed exceeds 2 meters/second, the competition record will not be recognized.

This reminds me of this year's Tokyo Olympic Games, Su Bingtian with 9.83 seconds to refresh the Asian record, popular nationwide. He had earlier run a time of 9.90 seconds at the 2018 IAAF Diamond League in Eugene, but this time was invalidated due to a tailwind and wind speed of 2.4 m/s.

We all know that when the wind is downwind, walking and riding electric vehicles are easy, and the headwind is very laborious. Of course, in the case of small wind speed we directly ignore the past, but formal sporting events can not. Because of the pursuit of fairness and professionalism, the subtle wind speed and direction should also be taken into account.

Having said that, we need to introduce the instruments that measure wind speed and direction.

Fengtu Technology is a professional manufacturer of meteorological environment monitoring equipment, and there are two products that can measure wind speed and direction.

The first is the hand-held anemometer, model FT-SQ2, which is a meteorological observation equipment that is convenient to carry, simple to operate, and real-time measurement of wind speed and direction. Based on the mechanical wind speed and direction sensor, wind vane and wind direction dial (magnetic compass) measure the wind speed in real time, and the three-ring rotating frame structure measures the wind speed, and the measured parameters are directly displayed digitally on the liquid crystal display.

The second is the ultrasonic wind speed and direction sensor, which is based on the ultrasonic time difference method of the weather sensor, because there is no mechanical structure, so greatly reduced the error range, integrated design, no need for on-site calibration, ASA material corrosion resistance does not change color.
