  • Product Code: Windcrane Wind Vane V20
  • Availability: In Stock
Estimated Dispatch: (Fri 11th Sep - Wed 16th Sep)
Delivery: Free Worldwide Delivery


Description

The WINDCRANE V20 wind vane is a high-accuracy wind direction sensor for use with the WINDCRANE wind monitoring system and use with boom wind.

How does a wind vane work? It measures wind direction by aligning itself with the wind, using its tail and potentiometer to provide precise directional readings.

Includes

  • V20 Wind direction vane with a 1m cable and M12 connector and Z mast
  • 10m extension cable with M12 connectors
  • U-bolt clamp

John Colwell, Crane Manager 04/05/2026

I have worked with the folks at WindCrane for the past several years.
… after we launched and fielded the anemometer system, I asked them to enhance their product by integrating a wind vane into their system to provide wind angle relative to the crane boom. They attentively listened, understood the value to the customer, performed the research/development, and deployed a new system that incorporates not only wind speed, but now wind angle to the boom… this is a MAJOR “gamechanger” as it opens up new possibilities for crane operations (if you know, you know).
Another WindCrane system enhancement (requested from the customer) is the integration of an inclinometer on the boom tip. With this, we can now see the relevance of the reported wind speed as we can now see remotely if the crane boom is on the ground or raised into the lift position (as reported by the boom lift angle).
Collectively, these enhancements demonstrate WindCrane’s ability to deliver a highly effective, continuously evolving remote monitoring solution that directly supports safer and more efficient crane operations.
I recommend WindCrane to any organization seeking a reliable, innovative, and customer-focused partner in crane monitoring technology.

Windcrane's accessory as wind direction sensor have transformed our interactions with environmental authorities. At Saria Group, where we manage diverse departments including animal food recycling, these tools provide crucial historical wind data. Now equipped with proof of odor dispersion, we engage confidently, ensuring our commitment to responsble practices.

We are using Windcrane Max unit wiith a solar battery on the top of wind turbines at a height approx. 135m. We need to be able to monitor wind speed and direction on the site, until we have grid power on sites. The units are very reliable. As far as data, the app and the website are very intuitive and pretty easy to use and set up.
