What is an anemometer and what does it measure?

An anemometer is a device used for measuring wind speed, and is also a common weather station instrument. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in meteorology. The first known description of an anemometer was given by Leon Battista Alberti in 1450.

How to use an anemometer?

Before using the anemometer,observe whether the pointer of the electricity meter points to the zero point.

  • Set the anemometer calibration switch to the off position
  • Insert the measuring rod plug into the socket,the measuring rod is placed vertically upward,the screw plug is pressed tightly to seal the probe,the “correction switch” is placed
  • Set the “correction switch” to the “zero position”,and slowly adjust the two knobs “coarse adjustment” and “fine adjustment” so that the meter pointer points to the zero position
  • After the above steps,gently pull the plug to expose the rod probe (the length can be selected according to need),and make the red dot on the probe face
  • After measuring for several minutes (about 10min),the above steps 3 and 4 must be repeated once to standardize the current in the instrument
  • After the test,the “calibration switch” should be placed in the off position.
  • How is propeller anemometer used?

    A propeller anemometer is used to measure gas velocity directly . The area of the stack cross section at the sampling location is used to calculate volumetric flowrate, and temperature and pressure measurements are used to correct volumes to standard conditions. 2. Apparatus Specifications for the apparatus are given below. 2.1 Propeller Anemometer .

    How does the anemometer work?

    An anemometer is a weather monitor instrument used to measure wind speed. The first crude anemometers were used to roughly measure wind speed hundreds of years ago, but today anemometers are highly accurate wind speed monitors that can provide data in a variety of ways.
