Velocimeter

A velocimeter is a device used to measure the speed or velocity of an object. It is commonly used in aviation, meteorology, and engineering to assess how fast something is moving. For example, in aircraft, a velocimeter (or airspeed indicator) measures the aircraft's speed relative to the air surrounding it. It works by sensing changes in air pressure or using other methods like radar or laser. The data helps pilots or engineers ensure safe operation and monitor performance. Essentially, a velocimeter provides precise speed readings critical for navigation, safety, and analysis.
