Calibration Services

ProfEC Ventus as calibration laboratory performs calibration of cup anemometers and wind vanes, entirely respecting the pertinent ISO/IEC 17025:2005, IEC 61400-12-1 and MEASNET standards 

Mandatory for any project

Next to our accreditation as Testing Laboratory, ProfEC Ventus GmbH also is accredited as Calibration Laboratory in accordance to IEC 17025 for calibration of Cup Anemometers and Wind Vanes incompliance with IEC 61400-12-1, CDV IEC 61400-12-1 Ed.2:07-2015 and MEASNET Cup Anemometer Calibration Procedure – Version 2. 

Currently worldwide only two companies can offer accredited calibrations of wind vanes, among which ProfEC Ventus, being the first and only one accredited for wind vane calibrations in accordance to the recent CDV IEC 61400-12-1 Ed.2:2015-07. 

Moreover we contribute to the proceedings of pertinent norms and regulations such as ISO/IEC 61400-12-1 Ed.2 and are working as Member of the German Calibration Service (DKD / PTB) as part of the group „Flow Measurands“ (Strömungsmessgrößen). 

All that makes us to one out of a few recognized entities worldwide that offer such high-quality calibrations of wind sensors. 

Our R&D department further improves measurement sensors and performs research on measurement and calibration subjects, always investigating and exploring new ways to improve the accuracy of measurement results.

Measuring precisely matters

None-calibrated sensors, same as sensors not calibrated in accordance to pertinent norms and guidelines, introduce unnecessary errors and uncertainties during interpretation of measurement results. 

The response of a sensor to the wind speed or wind direction precisely needs to be known, in order to measure as close as possible to the real physical value prevailing. 

That especially is the case for wind speed sensors, recognizing that wind speed has a cubic relation to the kinetic energy contained within the wind, which any wind project is supposed to harvest. 

Small errors introduced already can cause significant differences in the energy yield prognosis and uncertainties due to absence of a calibration or due to unsuitable calibration procedures. 

Both as a consequence cause sub-optimal or even prohibiting project financing terms. 

An experienced investor or bank will try to balance any uncertainties by an increased interest rate, increased guarantees to be given by the project owner in turn to secure the loan granted and/or an increased equity share to be provided. 

Considering that right from the beginning, enables to counter balance such risks and uncertainties by always maintaining a proper calibration of the measurement sensors. 

We in that sense do offer a competitive and attractive graduated pricing, depending on the urgency that a freshly calibrated sensor needs to be sent out to our Client and on the quantity of sensors to be calibrated for particular Clients during the year.
