Key Applications of Anemometers: An Introduction
Anemometers have a wide range of applications and can be flexibly used in all fields. They are widely used in industries such as power, steel, petrochemicals, and energy conservation. There are also other applications in the Beijing Olympics, such as sailing competitions, kayaking competitions, and field shooting competitions, which require anemometers to measure. Anemometers are already quite advanced, and in addition to measuring wind speed, they can also measure wind temperature and air volume. There are many industries that require the use of anemometers, and recommended industries include offshore fishing, various fan manufacturing, industries that require exhaust systems, and so on.
Anemometers can cause changes in wind direction in the atmosphere due to different seasons and geographical conditions. As the wind direction at the seaside varies day and night, there are also different monsoons 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, but there are also animal shaped ones, such as rooster shaped ones. The feather part of the anemometer will rotate with the wind. The anemometer should be installed in a place without buildings or trees that obstruct the movement of wind. The QDP series hot ball anemometer is used in various fields such as heating, ventilation, air conditioning, meteorology, agriculture, refrigeration and drying, labor hygiene investigation, etc. It can be used to measure the airflow velocity indoors and outdoors or in models. It is a basic instrument for measuring low wind speeds. 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 tiny glass ball with a nickel chromium wire coil for heating glass and two thermocouples connected in series inside the ball. The cold end of the thermocouple is connected to a phosphor copper pillar and directly exposed to the airflow. When a certain amount of current passes through the coil, the glass ball is heated to a certain temperature, which is related to the speed of the airflow. The temperature is higher when the flow rate is low, and lower when the flow rate is low.
