Over the past 15 years, we have specialized in the construction of meteorological towers (measurement towers), making us one of the leading suppliers in Europe today. We work for many of the major wind turbine manufacturers, installation companies, wind measurement firms, and energy providers.

Our close collaboration with major manufacturers and specialists in wind measurement has given us unique knowledge and expertise. Therefore, we can offer our customers professional advice and service to ensure they get the solution that meets their needs for accurate and reliable wind measurements.

Meteorological towers are an essential part of establishing wind farms. Measurements of wind speed, temperature, humidity, and pressure are crucial for determining the attractiveness of establishing a wind farm. Even after the wind farm is established, measurements must be taken so that the produced energy can be compared to the current weather conditions.

Accurate measurements are crucial for selecting the right turbines for the conditions. It has been observed in several cases that inaccurate measurements have had fatal consequences for the success and profitability of wind farms.

To ensure optimal wind measurements for our customers, we have tested our meteorological towers to determine how far from the mast wind measurements should be taken to meet the IEC 61400 standard of maximum 1% distortion of the wind. Therefore, we know precisely how long the booms should be to meet this standard – thus providing customers with accurate and reliable measurements.


The freestanding tower 

The freestanding meteorological tower is often used as a permanent mast in an established wind farm, where all essential meteorological values ​​are measured.

These measurements are used to calculate the efficiency of the wind turbines.


The guyed mast

Barduneret mast anvendes mest som midlertidig brug, hvor der ønskes præcise meteorologiske målinger på en lokation, hvor der påtænkes at opføre en vindmøllepark.

Masten demonteres ofte efter et til to år og kan genanvendes et andet sted.

A Temporary mast

Temporary measurement masts are used in various ways. Sometimes they are installed for periods ranging from 3 months to 3 years before wind turbines are erected, allowing wind conditions at different heights to be mapped. This means installing a mast precisely where the wind turbine will stand, and then also installing a permanent mast nearby. This provides wind measurements from two locations, increasing reliability. When the temporary mast is later removed and the wind turbine is mounted in the same location, the exact impact of the wind on the turbine is known based on continued measurements from the permanent mast. In large wind farms, there are usually several measurement positions to obtain both "up-wind" and "down-wind" measurements. Additionally, it is beneficial to have multiple masts positioned around the park to compare wind data from several locations and optimize turbine performance. It is also important that measurements are taken at the same height as the wind turbines produce power, as wind speed can vary significantly at different heights.


A permanent mast

Permanent measurement towers are often freestanding towers because they are very sturdy and can withstand wind and weather. They can be installed for up to 30 years and require minimal maintenance.

Freestanding meteorological towers from Carl C are designed to be built up to heights of 200 meters. The slim, streamlined design with solid round steel bars ensures minimal influence on the wind conditions around the mast, so the measurements are as accurate and reliable as possible. The towers are designed to withstand extreme weather conditions in coastal areas or in terrain that is completely flat without trees or other obstacles.

The design and calculation of towers from Carl C are carried out by external consulting engineers who have many years of experience and expertise in tower construction. The calculations are made according to norms such as Eurocode, Scandinavian, and English standards. Often, compliance with IEC standards is crucial for the structural calculations of the meteorological tower.
