How to choose the probe for wind direction anemometer
The wind direction anemometer is an instrument used to measure wind direction and wind speed in the environment. This instrument is mostly used in meteorological inspection or agricultural work as an official designated instrument for measuring wind direction and wind speed. Although wind direction and wind speed do not have as great an impact on plants as temperature, humidity, and illuminance, if timely prediction is not made, it will still have an impact on the yield of plants, especially for stem plants such as rice. Therefore, as agricultural modernization, we recommend the use of wind direction and anemometers to cooperate with agricultural production in order to obtain better production benefits. In addition, in the process of agricultural modernization, we use a lot of chlorophyll content analyzers. The chlorophyll content meter is considered to be one of the most powerful assistants in agriculture, because it can not only measure the chlorophyll content in plant leaves, but also measure the nitrogen content of plants at the same time, which is multi-functional.
Wind speed and direction recorders are used in many fields, especially in agriculture, where they avoid the impact of mutations in the environment on plant growth. In addition, the wind direction and wind speed monitor has multiple probes during the configuration process. It is best to measure according to the wind direction and wind speed in the environment. Although the probes are consistent, the probe sockets of different parameters can be interchanged without affecting the accuracy. However, using the corresponding probe according to the wind speed can more accurately guarantee the accuracy of the measurement results. So in the actual practice process, how do we choose the appropriate probe according to different wind speeds?
The flow velocity measurement range from 0 to 100m/s can be divided into three sections: low velocity: 0 to 5m/s; medium velocity: 5 to 40m/s; high velocity: 40 to 100m/s, but the wind direction and velocity monitor can Measure the wind direction and speed at low and medium speeds. The thermal probe of the wind direction anemometer is used for accurate measurement of 0 to 5m/s; the rotary probe of the wind direction and anemometer is ideal for measuring the flow velocity of 5 to 40m/s; and the pitot tube can be used in the high speed range Get the best results within. An additional criterion for the correct selection of the flow rate probe of the wind direction anemometer is the temperature. Usually, the temperature of the thermal sensor of the wind direction anemometer is about +- 70C. The rotor probe of the special wind direction anemometer can reach 350C. Pitot tubes are used above +350C. Through the selection of the probe, the accuracy of the measurement can be guaranteed to a large extent, and at the same time, the service life of the instrument can be extended, and the damage of the instrument caused by the custom of measuring too high can be reduced.
