The widespread application of anemometers
The application of anemometers is very extensive, and they can be flexibly applied in all fields. They are widely used in industries such as electricity, steel, petrochemicals, energy conservation, etc. There are other applications in the Beijing Olympics, such as sailing competitions, rowing competitions, field shooting competitions, etc., which require the use of anemometers for measurement. Nowadays, anemometers are relatively advanced, which can not only measure wind speed, but also measure wind temperature and airflow. There are many industries that require the use of anemometers, and recommended industries to use include offshore fishing, various fan manufacturing industries, industries that require exhaust systems, and so on.
Different seasons and geographical conditions of anemometers can cause the wind direction in the atmosphere to constantly change. As the wind direction at the seaside varies day and night, there are also different monsoon seasons in winter and summer. Studying wind direction can help us predict and study climate change. Studying wind direction requires the use of an anemometer. The design of anemometers is mostly arrow shaped, and some are made in animal form, like the shape of a rooster. The arrow feathers of the anemometer will rotate in the direction of the wind. The anemometer needs to be installed in an area where there are no buildings or trees that obstruct the movement of wind. The QDP series hot bulb electric anemometer is used in various fields such as heating, ventilation, air conditioning, meteorology, agriculture, refrigeration and drying, and labor hygiene investigations. It can be used to measure the airflow velocity indoors, outdoors, or in models. It is a basic instrument for measuring low wind speeds. This product was rated as a high-quality product in Beijing by the Beijing Municipal Economic Commission in 1987. The working principle of this instrument consists of two parts: a hot ball sensor and a measuring instrument. The head of the sensor has a small glass ball, inside which there is a nickel chromium wire coil for heating glass and two connected thermocouples. The cold end of the thermocouple is connected to a phosphor copper pillar, directly exposed to the airflow. When a certain amount of current passes through the heating coil, the glass ball is heated to a certain temperature, which is related to the speed of the airflow. When the flow rate is small, the temperature is higher, and vice versa.
