Understand that an anemometer essentially works by getting the wind to spin around three to five small plastic cups. The secret to learning how to use an anemometer to figure out wind speed lies in observing, paying attention and doing some calculations of your own.

In order to use an anemometer the ideal position for the device is at least 4 feet above the ground. It is also equally important to place your anemometer away from wind obstructions like buildings or trees. That way you can be sure to get an entirely accurate reading.

Keep your eye on the target cup and watch follow it as it revolves. The anemometer will have five cups and one of them will be of a different color so that it can be followed more easily as it revolves. Start the stopwatch and count how many times the target cups goes around in a minute. Record this number and then repeat two times, making sure to record the number of the times the target cup revolves.

Take the three readings and divide by three. The resulting number represents the average revolutions per minute. Although the actual wind speed of an anemometer is dependent upon its size, generally speaking every ten revolutions per minute is equal to one mile per hour.
To calculate the velocity of air in a mine, you can use a device called an anemometer. An anemometer measures the flow and speed of air, providing you with the velocity information. Simply place the anemometer in the air flow in the mine and it will give you a reading of the velocity.
An anemometer is typically used to measure wind speed, while a wind vane is used to determine wind direction. These instruments are commonly used in meteorology and weather stations to monitor wind conditions.
an anemometer can be measure based on the type you use therefore the units it can be measured in is knots, miles/hrs, km/hrs, ft/min or c and f
You can find out which way the wind is blowing by using a weather vane or by observing the movement of trees, flags or grass. Another option is to use a handheld anemometer to measure wind direction and speed.

meaning and use of propeler anemometer
An anemometer is used for weather forecasting by meteorologists.
It measures wind speed.
The Anemometer measures wind speed, not wind direction. Wind Direction is measured by the wind vane.
Anemometer is the instrument used to measure wind speed and direction.
The reason the anemometer is so important is because you use it to measure the velocity of the wind and to measure pressure of the wind ----
To measure the speed of wind.

Anemometer Improvement. You can use a thermometer too.
An anemometer with a wind vane is the right answer
an Anemometer measure wind speed so it would be used everywhere in the US and all over the world
