    The three-cup anemometer is specifically designed to accurately and reliably measure wind velocity under adverse environmental conditions. Wind speed sensor measures air velocity, outputs voltage and current signals by electromagnetic induction.

    Detail of 3-cup anemometer

    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 external plating spraying treatment, with good anti-corrosion, anti-leaching and other characteristics to protect.
    • Transmitter long-term use without rusting phenomenon.

    3-Cup Anemometer Output Characteristics

    • Pulses Output

    Characteristic transfer function:

    V = 0.667*F

    (where V = wind speed (m/s), F = output frequency (Hz) )

    • Current Output

    0~30 m/s 3-cup anemometer output current characteristics

    • Voltage Output

    Characteristic transfer function:

    V = U/ (full scale voltage - zero point voltage) * 30

    (where V = wind speed (m/s), U = output voltage (V) )

    • RS-485 Output

    lf the transmission distance is over 100m, please add a 120Q terminal matching resistances on the front endand back end of bus interface respectively. See the modbus communication protocol specification.



    The three-cup anemometer is widely used for data acquisition in boilers, refrigeration, HVAC, ventilation ducts, agriculture meteorological station, meteorologica monitoring for seaport, weather minitoring for expressway, wind power generation weather station.

    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 are the three cups on an anemometer?

    It consisted of three hemispherical cups each mounted on one end of horizontal arms, which in turn were mounted at equal angles to each other on a vertical shaft. The air flow past the cups in any horizontal direction turned the cups in a manner that was proportional to the wind speed.
