How to Replace the Cups on a MeteoWind 2 Anemometer
/QUESTION: How can I replace a broken cup on a MeteoWind anemometer?
ANSWER: MeteoWind anemometers use a special FRP material for the anemometer cups which has been tested down to -60 °C for impact absorption from flying debris. Instructions on how to replace an anemometer’s cups can be downloaded in the following PDF: MeteoWind Service Manual
The following instructional video and animation show how the anemometer rotor head and cups are assembled and held together to make easy field repair possible with just a single 8 mm socket head hex wrench. Only 2 Nm of torque is required to tighten the nut holding the cups.
Note: The rotor head is made of an aluminum alloy, hence maximum torque limits must be respected to avoid stripping the threads.
