V200A Ultrasonic Wind Speed/ Direction Sensor

The Lufft V200A simultaneously measures wind speed & direction with an integrated electronic compass for corrected wind direction on moving platforms.


  • Four ultrasound sensors take cyclical measurements in all directions

  • Easily mounts to 2" diameter pipe with integrated bracket mount & U-bolts

  • SDI-12 output for integration with data loggers
Ultrasonic wind sensor / wind velocity / wind speed / wind direction/ acoustic virtual temperature

Extremely precise and maintenance-free measurement of wind velocity and wind direction as well as calculation of acoustic virtual temperature.

The ultrasonic wind sensor is designed without mechanical parts as opposed to traditional “cups and vanes”.

Robust design and precise measurements allow for efficiency and accuracy of project control. Heated for use in cold weather climates.

Recommended for:

  • Meteorology
  • Building automation
  • Wind profile measurement
  • Small wind turbines

The following outputs/protocols are available:

  • NMEA
  • UMB
  • 4.. 20 mA, 0...10V, frequency (analog)
  • SDI12
