Anemometer is a device used to measure wind speed. It is small and light, easy to carry and assemble. According to the working principle, it can be roughly divided into mechanical wind speed sensor and ultrasonic wind speed sensor. It can effectively obtain wind speed information. The shell is made of high-quality aluminum alloy profiles …

The anemometer measures the airflow velocity in the pipeline: Practice has proved that the 16mm probe of the anemometer is the most widely used. Its size not only ensures good permeability, but also can withstand flow rates up to 60m/s. As one of the feasible measurement methods, the measurement of airflow velocity in the pipeline, …
Probe selection for anemometers The flow velocity measurement range from 0 to 100m/s can be divided into three segments: Low speed: 0 to 5m/s. Medium speed: 5 to 40m/s. High speed: 40 to 100m/s.The thermal probe of the anemometer is used for precise measurements from 0 to 5m/s.The rotor probe of the anemometer is ideal …
Wind affects our life all the time. In modern society, with the development of science and technology, wind speed and direction sensors used to measure the direction and size of the wind have been widely used in meteorological monitoring. At present, there are many cup anemometers on the market. Regarding how to distinguish the quality of …
1) Generator-type Cup Anemometers This type has a small AC generator coupled to its axis. The wind turns the cups and the generator to generate a voltage proportional to the instantaneous wind speed, and the signal is transmitted to the indicator (Figure 1). The CR integrated circuit calculates the average wind speed as the circuit …
There are two types of rotating anemometer: the cup anemometer, which has three or four cup wheels attached to the rotating axis, and the propeller anemometer, which has propeller blades. Both types rely on the principle that the revolution speed of the cup or propeller rotor is proportional to the wind speed. Rotating anemometers can …
In many occasions, such as mines, forests, weather monitoring, etc., ultrasonic anemometers are required. The ultrasonic anemometer is designed based on the principle of ultrasonic vortex. The ultrasonic transducer is used to send and receive signals, and then equipped with a hardware processor chip. As a controller, it can realize the functions of wind speed …
If a wind measuring instrument (anemometer) becomes faulty or is not available, wind can be estimated by visual means such as observing smoke as a guide to wind speed and using the Beaufort Scale (Table 4.2).It is also possible to estimate wind direction by observing the flow of smoke or the movement of a flag. …
The monitoring of mine wind speed is an important factor to ensure safe production in mines. The working conditions of mines are special and the working environment is complex. Wind speed measurement is an important content in mine safety. The real-time display of the wind speed and air volume of the roadway is an important …

AgricultureIn the field of agriculture, wind direction and wind speed play a very important role. They play a key role in plant growth and development to pollination, including the spread of pests and diseases in farmland, which are also inseparable from wind speed and wind direction. Physical damage to agricultural products, such as crops falling …
