Calibration in accordance to MEASNET/IEC 61400-12-1 at a flow speed range of 4 to 16 m/s with 13 measurement points at a tilt angle of 0°. WindGuard has also established a fixed yaw orientation for each anemometer type to achieve a high repeatability of measurements results. DAkks / ILAC accredited calibration laboratory according to ISO 17025:2018 The wind sensor...

The European Commission introduced an implementing Regulation (EU) No 595/2009 of the European Parliament and of the Council as regards the determination of the CO2 emissions and fuel consumption of heavy-duty vehicles and amending Directive 2007/46/EC of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011.

The classification at WindGuard includes: - Standard MEASNET/IEC61400-12-1:2017 calibration of anemometers - Measurement of tilt angular response characteristics - Measurement of directional characteristics - Measurement of influence of temperature and air density -...

The procedure for the calibration of tilt response is in accordance to IEC 61400-12-1. The wind sensor is slowly tilted between -30° and 30° at a fixed wind speed of approx. 8 m/s and fixed yaw angle. The benefit of a continuous tilting is that the response of the sensor at any angle is considered. Therefore on this approach surprises at a non-evaluated angle can be avoided....

During a Wind Direction calibration in accordance to the IEC 61400-12-1, the wind sensor is slowly yawed for a whole revolution and back at a fixed flow speed of approx. 8 m/s and a fixed tilt angle of 0°. A stepwise calibration is possible, but not suggested from WindGuard. A continuous yawing considers the response of the wind sensor for each wind direction. For example,...
