    Three-cup anemometer for sale with 0-45 m/s measurement wind speed. Wind cups of the wind gauge are made of carbon fiber, with high intensity and low starting threshold. The signal processing units are built in the housing shell. It can be widely used in meteorology, marine, environmental monitoring, weather station, airport, harbor, laboratories, industrial and agricultural areas.

    Wiring-free design

    • The upper and lower wind speed limits can be set on the phone, and when the wind speed reaches the upper and lower limits, the phone will be alerted.
    • The phone monitors the current wind speed value in real time and displays the current wind speed.
    • In the cell phone software, you can check the real-time wind speed value at any time.

    The digital anemometer can be widely used outdoors (such as riding), and for measuring wind speed and air volume. So the vane anemometer is widely applied to windsurfing, outdoor measurement, navigation survey, offshore fishing survey and electric power measurements, shooting, model plane flying, etc outdoor activities. It is also appropriate for industrial and family use, normally in conjunction with dust and fume extraction devices, heating and air conditioning systems, etc, measuring wind speed and air volume.

    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: What is a 3-cup anemometer?

    The 3-Cup Anemometer is a traditional type, sensitive sensor for horizontal wind measurement. All 3-Cup Anemometers are constructed with lightweight and UV-resistant plastic cups.

    Superior performance
    I recently purchased a Cup Anemometer, a three-blade cup anemometer with a 0 to 45 m/s wind speed range and RS485 output.
    I connected it to my data acquisition system and it was very easy to get real-time wind speed data. This feature is very useful for applications that require monitoring and recording of meteorological data.
