The use of wind speed sensors in the marine field can usually be divided into two areas: ocean and offshore: Oceanic areas: Most of the ocean storms actually originate from the distant seas, so setting up a meteorological observation platform at this location can play a role in early prediction. At present, in order to …
The working principle of cup anemometer The wind cup wind speed sensor is a very common anemometer, which was first invented by British Robinson. The induction part is composed of three or four conical or hemispherical empty cups. The hollow cup shell is fixed on a three-pointed star-shaped bracket that is 120° to each other …
Although it is known to contain inaccuracies, Kent et al. (1993) used the List of Selected Ships (WMO, 1990) to estimate that, at about that time, 70% of the global VOS fleet provided visual estimates, 22% used fixed anemometers, and 8% used hand-held anemometers. Which method was used depended principally on which country’s meteorological agency …
As anemometer sensors operate in outdoor environments and are exposed to severe weather conditions, they deteriorate relatively quickly. To ensure stable, high-accuracy observation, anemometer maintenance should be carried out periodically. This section describes general points to note when performing maintenance and repairing the sensors of anemometers. Strictly speaking, it is not possible to repair anemometers …
The handheld digital vane anemometer can be used to monitor the wind direction and speed in the fields of meteorological monitoring, agricultural and forestry crop planting, navigation, and aviation. The digital anemometer consists of a strut, a wind vane, a wind cup and a wind direction and wind speed sensor. The wind cup can measure …
Wind affects our lives all the time. In order to detect the dynamics of wind, wind speed sensors and wind direction sensors appear. In the field of construction engineering, most tower cranes are usually equipped with anemometers. Its existence allows the crane to issue an alarm when the strong wind affects the work of the …
At present, there are two types of equipment for monitoring wind speed and wind direction: one is an anemometer with a mechanical structure, and the other is an anemometer with ultrasonic measurement. These two types of wind speed and direction sensors are two common devices in daily life. What are the similarities and differences between …

Traditional mechanical wind speed and direction sensors have rotating parts, which are prone to wear and tear. The mechanical structure may be damaged by bad weather, and sand dust and salt spray will also cause corrosion. At the same time, due to the existence of friction, the mechanical anemometer will not be able to drive …

Measurement location selection The determination of the wind speed and air volume in the ventilation duct is obtained by converting the measured pressure. To measure the real pressure value of the gas in the pipeline, in addition to the correct use of the anemometer, the reasonable selection of the measurement section and the reduction of …

People often ask that the received signal is very stable when the wind speed is below 20 m/s, but when the wind speed exceeds 20 m/s, the anemometer received signal starts to shake, and the measurement time difference is hard to handle, etc. First, let’s analyze several situations that cause signal instability. ①Sound wave direction …
