Ultrasonics / Ultrasonic Anemometers for Wind Energy Assessments

Ultrasonics

Ultrasonic anemometers measure the horizontal wind speed and direction as well as the acoustic virtual temperature. However, because of their high power consumption, a connection to mains power supply is required and their application at self-contained, solar-powered measurement systems is not feasible. Ultrasonics offer excellent performance ratings at well-powered measuring stations. Ultrasonics are mostly applied for wind farm monitoring, on wind turbines and on offshore projects. Most ultrasonic anemometers can be fitted with electronically regulated heating.

In order to pool competences in the field of flow measurement and meteorological measurement technology, Ammonit Measurement GmbH and WIND-consult GmbH founded the Ammonit Wind Tunnel GmbH with headquarter in Bargeshagen near Rostock (Germany). Ammonit Wind Tunnel has been accredited by the German accreditation body (DAkkS) as independent calibration laboratory according to DIN EN ISO / IEC 17025. Ammonit Wind Tunnel is member of the MEASNET group. In its own wind tunnel the company calibrates wind speed sensors according to IEC 61400-12-1 and MEASNET for wind energy assessments.
