    Q1: How do you ensure accuracy of anemometer?
    A1: To make sure anemometers are reliable and precise, they should be regularly calibrated. This is the procedure of checking the accuracy of a measuring instrument – as well as the adjustment to align it with the standard. The process allows equipment to produce more accurate results than would've otherwise been possible.

    Q2: What affects an anemometer?
    A2: The higher the wind speed, the more power is required to keep the wire at a constant temperature. Wind speed can also be determined by measuring air pressure. (Air pressure itself is measured by an instrument called a barometer.) A tube anemometer uses air pressure to determine the wind pressure, or speed.

    Q3: Does an anemometer measure wind direction?
    A3: An anemometer looks like a weather vane, but instead of measuring which direction the wind is blowing with pointers, it has four cups so that it can more accurately measure wind speed. Each cup is attached to the end of a horizontal arm, each of which is mounted on a central axis, like spokes on a wheel.

    Tips: How does a hot-wire anemometer measure velocity?

    A Hot Wire Anemometer is an instrument for measuring velocity and direction of fluid (in this case air) by measuring heat loss of an electrically-heated wire placed in the air stream. When placed in an air stream the heat is transferred from wire to the air and the temperature of wire reduces.

    Compact, light, durable anemometer
    I bought this thermal anemometer to replace my broken one. The anemometer is cheap and it worked well and gave me good information on what I needed.
