Dear Reader,

2015 has been a great year for the wind and solar industry. More and more countries are active and develop renewable energy strategies. Meanwhile wind and solar energy significantly contribute to the global energy mix. The global outlook for renewables is encouraging. We look forward to a green future :-)

Before green energy is efficiently produced, the local conditions should be assessed. For accurate measurement, calibration plays an important role. We recommend calibrating relevant wind and solar sensor, e.g., anemometers, wind vanes and pyranometers. Read our news to learn more about calibration, certificates and sensor configuration.

ammonit calibration web

In order to perform an IEC- and MEASNET-compliant wind measurement campaign, cup anemometers have to be calibrated. IEC 61400-12-1 describes the calibration in detail. According to the IEC, cup anemometers shall be calibrated before and recalibrated after the measurement campaign. The difference between the regression lines of calibration and recalibration shall be within ±0.1 m/s in the range 6m/s to 12 m/s.

Calibration is a very complex procedure. Only IEC 17025 accredited institutes should perform calibrations. For wind sensors the MEASNET accreditation is an additional indicator for high quality calibration institutes. Ammonit cooperates with leading calibration institutes. We can arrange the calibration or recalibration of your sensors. Just get in contact with us: Cette adresse e-mail est protégée contre les robots spammeurs.

The calibration certificate documents the traceability to national standards according to the International System of Units (SI). Each calibration certificate refers to a sensor with unique serial number, which is also important for the recalibration after the measurement campaign. The document includes a number of important details, e.g.,:

Calibration mark
A unique ID of the certificate refers to the calibration institute and the calibration time.

Linear regression analysis
The linear regression analysis is the central element of the calibration certificate. It provides correlation coefficient R², as well as slope and offset values, which have to be entered in the Meteo-40 web interface for the statistics calculation.

Achieved compliance
Indicates the compliance with common guidelines / standards, e.g., MEASNET.

The most important details are the slope and offset values stated in the linear regression analysis. These values are necessary for sensor configuration and statistics calculation. However, the calibration certificate also includes details about the wind tunnel and the ambient conditions during the calibration.

 How to configure calibration values in the Meteo-40 web interface

You can conveniently configure all sensors connected to the Meteo-40 via its web interface. Meteo-40 includes a comprehensive sensor library with common instruments used for wind and solar measurement. After selecting a sensor type and measurement instrument, the web interfaces asks for slope and offset values, as well as the measurement rate and the channel. Meteo-40 automatically recommends standard values, but slope and offset have to be filled with individual sensor data.

You can easily configure your sensors in the Measurement → Sensors menu of the Meteo-40 web interface.
