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: Are ultrasonic anemometers accurate?
Yes, because ultrasonic wind speed measurement sensors have no moving parts, the measurements are immediate and extremely precise.
