An industry standard anemometer. An optical sensor ensures no contact measurement with a high pulse output frequency for quantifying turbulence. The anemometers are individually calibrated in-house by Vector. They require 1mA @ 12 V.
The anemometer is identical to the A100LK , apart from a reed switch output which has a lower pulse output frequency but requires no power. It is an ideal instrument for measuring 10 minute average wind speeds.
The start up speeds of the Vector anemometers is as low as 0.1 m/s, compared with Second Wind anemometers which only start producing a reliable output at 4 m/s. The bearings of vector anemometers ensure reliable measurements across the wind speed spectrum.
Wind Measurement International supply sensor arms and booms which provide Measnet recommended mounting and satisfy IEC standards. WMI booms exceed Garrad Hassan recommended mast-anemometer separation distances, minimising mast shelter effects.
