Hint:
An anemometer is a tool used to measure wind speed and direction. And it's a standard weather station. The word is derived from the Greek word anemos, meaning wind, and is used to describe any wind speed instrument used in the sky.
Complete step by step solution:
Anemograph (Anemograph) that provides continuous tracking of the direction and speed of the upper air. In the Dines tube anemograph, air pressure is applied to the opening of a tube arranged as a vane to withstand airflow. The pressure is transmitted by a floating tube carrying a pen, the length of which indicates the speed of the air. The anemometer has changed slightly since its development in the 15th century. Leon Battista Alberti is said to have invented the first mechanical anemometer in 1450. In the centuries that followed, many others, including Robert Hooke, invented their own translations, some even mistakenly being called inventors. In 1846, John Thomas Romney Robinson developed this design by using four round cups of machine wheels. One of the other types of mechanical velocity anemometer is the vane anemometer. It can be described as a windmill or a propeller anemometer. Unlike Robinson's anemometer, the vertical rotation axis, the vane anemometer should have its own axis in proportion to the direction of the wind and therefore horizontal. In addition, as the air varies from one to the other and the axis must follow its change, a vane or other means to accomplish the same purpose should be used.
Hence, the correct answer is option B.
Note:
The simplest type of anemometer was invented in 1845 by the Rev. Dr. John Thomas Romney Robinson, of Armagh Observatory. It consisted of four cups on the east side mounted on the horizontal arms, placed on a straight shaft. The air flow passed the cups in any horizontal direction and turned the shaft at a rate almost equal to the speed of the wind.
