ZephIR DM
TURBINE-MOUNTED, AND THE ONLY LIDAR TO GIVE YOU FULL SWEPT ROTOR WIND MEASUREMENT UPWIND OF A WIND TURBINE OUT TO RANGES OF 10 METRES TO 300+ METRES.
 
 
FEATURES

• Go beyond any other available measurement technique to measure, optimise and benchmark turbine performance.
  All with the added functionality of groundbased deployments from the same core product
  with its unique Dual Mode capability.
• Industry-backed IEC equivalent power curve procedure and measurements at 2.5 rotor diameters
  or as close as 0.5 rotor diameters.
• A unique ability to electronically compensate for nacelle motion guaranteeing measurements
  within +/- 1% of hub height.
• Capable of measuring the full shear and veer wind profile, delivering a true measurement of the inflowing wind
  from the full 360 degree turbine rotor swept diameter.
• Quantify turbine performance for example identify opportunities for yaw realignment,
  spot changes in nacelle sensor calibration and schedule blade erosion maintenance.
