Cup Counter Anemometer

• Wind capture: Three conical cups on a spindle are exposed to the wind and rotate freely in a horizontal plane.
• Mechanical coupling: The rotation of the cup rotor is transferred to a worm and gear mechanism, which turns a revolution counter.
• Recording distance: The counter directly displays the total "run of wind" (the distance wind has traveled) in kilometers, often with tenths of a kilometer indicated.
• Calculating average speed: By taking counter readings at the start and end of a period (e.g., 3 minutes or 24 hours), the mean wind speed can be calculated by dividing the total distance (wind run) by the time elapsed.

Key Features:

• Three-cup rotor: The rotor assembly typically consists of three conical cups made of copper or other suitable materials.
• Mechanical counter: A five-figure counter is used to record the wind run in a waterproof housing.
• Worm and gear drive: A precise worm and gear system provides a fixed ratio between the cup rotors revolutions and the counters rotations.

• Wind Run measurement: The primary function is to measure the total distance the wind travels, from which the average speed is derived.

Q: How does a cup counter anemometer measure wind speed and direction?

A: The anemometer operates by having its cups rotate on a spindle as the wind blows. It counts the number of rotations and translates this into wind speed calculations. Direction sensors may be included to ascertain the winds origin.

Q: What is the process for retrieving wind data from this anemometer?

A: Wind data is stored in the anemometers sizable internal memory (up to 30 GB or 2000+ readings). Users can connect via USB or Mini USB interfaces to download all recorded readings to a computer or data logger for further analysis.

Q: When should this anemometer be used for best results?

A: This device is optimal for weather monitoring, site surveying, and industrial safety checks in environments ranging from -40C to +100C. It functions reliably all year round, provided it is powered by a 12 VDC source and positioned in unobstructed areas outdoors.

Q: Where is the ideal location to install the cup counter anemometer?

A: Install the anemometer in open areas away from walls, trees, or buildings that may block or alter wind flow. Elevated positions such as rooftops or open mast tops facilitate more accurate wind measurements.

Q: What benefits does the integrated alarm offer?

A: The built-in alarm provides real-time alerts when wind speed measurements exceed preset levels. This feature enhances operational safety by notifying users of hazardous conditions instantly.

Q: How is this anemometer powered and how long can it operate on standby?

A: It is powered by a 12 VDC power supply (220-240V input), and with no internal battery required, it remains operational as long as connected to a suitable power source. Its standby time when disconnected is up to one day.

Q: What materials and build quality ensure longevity for this anemometer?

A: Crafted from corrosion-resistant aluminum, the anemometer is designed to withstand harsh weather, temperature fluctuations, and continuous outdoor use, ensuring a long operational lifespan.
