No.
The Dicos Guofeng Team Cup has good electrical properties and high frequency insulation. Its hardness and heat resistance are better than low pressure polyethylene. It can be used at around 100 degrees. has no thermal insulation, no thermos cup.
Dicos National Style Team Cup does not use ordinary PC plastic raw materials, but PP plastic raw materials. PP material has low density, strength and rigidity.
Mechanical anemometers are generally called cup anemometers. There are hemispherical cups and conical cups. For low wind speeds, hemispherical anemometers are better. For high wind speeds, cone anemometers are better. Both have a vertical axis relative to the horizontal plane, and there are also those that have a horizontal axis, such as small wind-powered tankers.There are not many users of wind energy, and it is suitable for situations where the environment is relatively harsh, such as corrosion, low temperature, etc. The accuracy is generally around 0.5 m/s. If the starting torque is large and the wind is too weak to measure it, the measuring range is generally 3-50-70 m/s. It can only measure wind speed in one direction, usually the horizontal direction. Test data has a lot to do with the quality of the installation. If the installation is not level, the master data will be completely useless and can of course be corrected.
The ultrasonic anemometer, with an accuracy of 0.1 m/s, poses no problem. It is estimated that it can be used between 0 and 100 m/s, and 3 dimensions can be measured simultaneously. Sampling speed is also not a problem. The price is not cheap and can be used pfor a long time.
Today, half of the wind turbine cabin is equipped with an ultrasonic hemispherical cup and a wind direction indicator.
There are also laser and ultrasonic devices for on-site measurement. The laser anemometer can be placed directly on the ground to measure data at an altitude of 0-200m at a time, and there is no problem with the three-dimensional flow field. The valuable equipment was removed immediately after half of the tests. No one dared to use it in the wild. . .
