Metek - Model uSonic-3 -Multi-Path Ultrasonic Anemometers
The ultrasonic anemometers uSonic-3 Class A MP and uSonic-3 Cage MP represent an innovative step forward to highest performance in atmospheric turbulence sounding. Based on the well proven METEK ultrasonic sensor family uSonic-3 the design of the sensor head enables the user to perform three independent measurements of the 3D air flow quasi-simultaneously using only one sole sonic anemometer by arranging each sonic transmitter to three opposite sonic receivers.
Metek’s ultrasonic anemometers uSonic-3, uSonic-2 and uSonic-1 have acquired wide acceptance as measuring sensors for wind and turbulence. uSonics are made from stainless steel and allow an efficient heating to prevent icing. uSonics are used in eddy-flux installations, in operational networks, at wind turbines or in any industry. A convenient user interface offers a flexible adaption to customer needs and includes a quick look of uSonic anemometer data.
This provides redundancy in horizontal wind components measurements and allows a selection of the most advantageously positioned transmitter-receiver couples. Furthermore, three directly measured vertical wind components are available.
The sensor outputs 9 radial components, 9 sonic temperature measures and 3 Cartesian wind components (x, y, z) as raw data or as averaged data with adjustable averaging intervals.
- Unique “Multi-Path” measuring technique
- 3 x 3D Sonic arrays in one sensor head
- 3 x 3 = 9 Radial wind components
- 3 x Directly sensed vertical wind component
- 3 x 3 = 9 Acoustic temperatures
- Minimum flow distortion by optimized design of sensor head and sonic transducers
- Online control and dynamic adjustment of signal gain
- Embedded 2-axis inclination sensor (option)
- Internal mass storage on SD card (option)
- Convenient communication and data output by RS422 and Ethernet ports
- Remote control of system performance
- Ideal instrument for scientific applications and eddy covariance sites
