These test instruments are known as anemometers. There are three methods used to measure the flow velocity:Īirflow measurement instrumentation is one of the most effective methods to test and confirm components. So, the flow rate as a time-dependent value is essential. Since most production systems have a continuous operation, the measured values must indicate the instantaneous conditions or the instantaneous values. Measurement technology provides devices for optimizing production processes and dosing operations. Remember that the wind speed is not constant it fluctuates all the time. Then Anemometer gives instant data about wind speed on a digital display.Ī decent anemometer will bounce a wind speed reading exactly to about ☐.5 m/s (☒km/h or ☑mph), but that is often far more precise than you need. Like small wind turbines, they use small propellers to control their generators instead of rotating cups-the generator links with an electronic circuit. Propeller anemometers work in much the same way. In the new inventions, the wind vane has directional indicators beneath the arrow associated with the geographic directions. The side with the larger area is blown away from the roller so that the smaller side with the pointer rotates to face into the wind direction. During this procedure, we also count the placement of surface area that is unequally divided. The wind vane design is constructed to attract the center of gravity directly over the pivotal axis so that the pointer moves freely at its desired axis.

For more historical facts and more information about other new technologies used in anemometers, please the following link on Brief History of Anemometer blog post. Andrews Pflitsch made the latest development in anemometers, including the sonic anemometer, in 1994. Numerous others developed later versions of the anemometer.ĭr. He made it more accurate and easier to measure wind speed. However, Leonardo da Vinci reinvented the device. Leon Battista Alberti invented the anemometer around 1450.Unexpectedly, it was changed little from its original invention in the 15th century! It still uses mechanical movement to measure the rate of movement and then presents the information. This wind speed instrument is used in meteorology or aerodynamics to detect the weather casting. The word anemometer is derived from the Greek word “anemos,” which means wind. It is also called a mutual weather station instrument. A digital anemometer is a device that measures wind speed and direction.
