The Ultrasonic Anemometer uSonic-3 Class A represents the high precision solution of METEK’s ultrasonic sensor family. It has been designed to meet the scientific needs of small scale turbulence measurement or mast
instrumentation.
 
An embedded 2-axis inclination sensor (option) provides accurate tilt angles of
the sensor head. A 6 m cable connects the sensor head to the sensor
electronic.
