wind speed measuring instrument application

the wind of the formation of image point metaphor, as an inflated balloon if there is no good, it is the atmospheric pressure outside ( High pressure) Will make the air discharge, then the balloon will accompany poop-poop sound dancing in the air side headwind for smaller, so the air in the atmosphere will movement to low pressure to form the wind.

anemometer application is very extensive, can apply, in all fields, are widely used in electric power, steel, petrochemical, energy saving etc, and other applications in the Beijing Olympic Games, sailing, rowing race, the wild shooting games and so on all need anemometer is measured. Now the anemometer is more advanced, in addition to measure wind speed at the same time can also measure air temperature, air velocity. There are a lot of industry needs to use anemometer, it is recommended to use the industry: sea fishing industry, all kinds of fan manufacturing, need convulsions of exhaust system, etc.

anemometer different seasons and different geographical situation, can make to the atmosphere wind direction changes constantly. Such as the beach day and night the wind is different, the winter and summer monsoon are different. Research direction of the wind can help us to predict and study of climate change. Research direction you need to use the anemometer. The design of the anemometer is dart more, also have made animal forms, like a rooster modelling. Anemometer arrows feather part will be the wind to turn. Anemometer device in no buildings or trees, such as blocking the wind moving place. Purpose and scope of QDP series hot bulb electrical anemometer, used in heating, ventilation, air conditioning, meteorology, agriculture, refrigeration dry, labor health survey and so on various aspects, requires the determination of indoor and outdoor or model can be used when air velocity, is a kind of measuring basic instrument of low wind speed.

in 1987, the product has been Beijing municipal economic commission awarded the quality product of Beijing. The working principle of this instrument by the hot bulb sensor and measuring instrument of two parts. Sensor head has a tiny glass ball, burn with heating glass ball nichrome wire coil and two thermocouples. Connection of the cold junction of the thermocouple in phosphor bronze pillars, directly exposed to the airstream, when a certain size of electric current through the heating coil, glass ball is heated to a certain temperature, the temperature and air flow rate, flow velocity hours at higher temperature, and temperature is low.
