Used to measure wind speed and wind velocity.Distortion may occur in the anemometer due to the strong winds.The main drawback is, the anemometer may get damaged due to the strong winds.It is utilized as a climate checking station. As it is a climate station device, it can detect, estimate, and gives information about the wind.It is available in different sizes and shapes.It consumes less power according to its cost and provides precision during the measurement.It is mainly used to measure speed, pressure, and direction of the wind.It is again divided into plate anemometers and tube anemometers To measure the pressure of wind, the pressure anemometer is used.Depending on the type of measurement, the anemometers are classified into the following types listed below.įor measurement of the velocity of wind, the velocity anemometer is used. It can also be utilized during the HVAC installation of air conditioners to measure the airflow. The instrument that measures the wind pressure, wind speed, and temperature of the air is known as Anemometer.

Other types of anemometers are used to calculate and measure the speed of the sound waves. Now compare the air pressure inside the glass tube and outside the glass tube to calculate the wind speed. To measure the air pressure inside the glass tube, close the one end. Take a glass tube to measure the air pressure. It determines the speed of the wind by using air pressure. These types are sensitive and mainly used in low wind speed measurements. The wind speed is calculated at the rate at which the hot-wire gets cooled down with respect to wind flow. If the speed of the wind is high, then more input power is required to maintain the wire at a constant temperature. The amount of power given to heat the wire is used to calculate the speed of the wind. When the thin hot-wire, which is electrically heated is placed in the wind, it gets cooled gradually. Its working is based on the rate of cooling the hot-wire. This is also known as thermal flow type or constant current type, which has an ability to measure both pressure and speed of the wind. Windmill types are also known as vane type or propeller type. Similarly, windmill anemometer also measures the speed of the wind based on the revolutions counted. In order to maintain the temperature of the wire constant, the power should be increased. The wire, which is heated electrically is placed in the airflow gets cooled down due to the increase in the flow of air. That means the speed of the airflow measures the rate of cooling. The working principle of hot-wire type depends on the rate of airflow, that cools the heated object. In the same way, the digital type is also an electromechanical device, that works on the same principle. We know that a tachometer converts the mechanical energy into corresponding electrical pulses to monitor the speed of the motor digitally.

It works on the principle of converting mechanical energy into electrical energy as the tachometer does. The anemometer working principle is simple and there no change since 1846. It is a cup-type, which is the most widely used by researchers and physicists. The basic anemometer diagram is shown below. So, it is also known as a climate checking instrument. Worldwide researchers, physicists, meteorologists, and educational institutions use this instrument to measure the speed, velocity, direction, and pressure of the wind.Īnother purpose of the anemometer is, it is used to estimate the climatic conditions and gives the information about the wind speed and direction. It is generally called a meteorological instrument or wind speed meter. The physicists also this device to know the direction of airflow. This instrument is mostly used by the meteorologists, to study whether conditions. What is Anemometer?Īn instrument that is used to measure the speed, pressure, velocity, and direction of the wind is known as Anemometer. This article gives a brief description of the anemometer and its working. For example, The laser types are used by aerospace engineers, and physicists to measure the speed of the wind around vehicles, and airplanes. These are used in many applications like monitoring the weather conditions, measure the air pressure, measures the velocity, and speed of the wind measures the speed of the airflow, etc. It is a meteorological device that can estimate whether conditions. The design and its working principle didn’t change over hundreds of years. Later on, many changes are made and invented different types of anemometers to measure wind speed and pressure more accurately.

The first mechanical anemometer is invented by Leon Battista Alberti, who was an Italian artist and an architect in the year 1450.
