met masts

wind measurement masts and self-supported wind measurement towers

A measuring mast is a stable structure designed to accom- modate various meterological sensors at a range of heights. It is used primarily to measure wind speed and direction, but also to measure other parameters such as temperature, hu- midity, atmospheric pressure and precipitation.

The data acquired by the measuring masts allows for the pre- cise estimation of wind energy potential and for the making of informed choices when selecting the type and model of wind turbine for a given location.

We offer:

• two types of measuring masts: 

— lattice (30 - 160 m) 

— telescopic/tube (50 - 100 m)

• self-supprted towers (120 m)

Self-supported wind measurement towers

Wind measurement with a traditional met mast still is the state of the art – carefully planned and installed a met mast still produces the lowest uncertainties of all wind measurement methods. The weight of a typical measurement system is comparatively low, and that is why the mast which carries the measurement system is a rather slender, guyed structure with guy wires anchored to the ground in a certain distance from the mast. This type of mast is sufficient and cost effective, but in certain cases there is not enough space available to anchor the guy wires. Specially for this cases Windhunter designed a unique self-supported tower.

Our self-supported wind measurement towers comply with IEC 61400-12 standards and can be equipped with the same high quality measuring systems as traditional guyed met masts. Although self-supported the structure is still slender enough to keep the influence on the anemometers and wind vanes as low as possible as described in the IEC 61-400-12 standard. There is no need for extremely long booms for the sensors, which would be prone to vibrations and movement due to wind force and gusts.

Typical applications for self-supported wind measurement towers are measurement campaigns at sites, where a high quality measurement is needed (e.g. due to complex terrain), but space for construction is limited, so that anchors can’t be set:

  • Wind measurement at narrow mountain ridges
  • Wind measurement in complex terrain, where the vertical height between the anchors is too high
  • Wind measurement offshore 
  • Wind measurement in forests with certain protected trees which can’t be cut down for construction of the anchors
  • Wind measurement on farm land which should be used for farming during the measurement period (you can’t use farming machines underneath the guy wires of traditional met masts)

Our self-supported towers are available up to 120 m height, the construction can be easily adapted for different sites and different wind and ice loads. For each site we provide an individual static calculation according to the site specific conditions and the respective building codes, and if necessary we adapt the construction and dimensions of the tower accordingly. If you have a certain project or a site where you are planning to build a wind farm we can provide with a specific offer. If you have any questions please don’t hesitate to call us or contact us via email!
