MeteoWind Compact Anemometer

WHY ELLIPTIC CUPS ARE BETTER

 
 elliptical cup

Elliptical cup shape

Patented elliptical design offers a larger wind blown area than circular and conical cups for higher aerodynamic torque to overcome bearing friction. Result is more consistent anemometer response throughout the complete air temperature range.

Benefits

  • Low starting speeds

  • Long-term dirt, dust and sand resistance created by the use of larger bearings which offer long-term measurement stability not effected by dirt

  • Reduces effects of rain and snow on anemometer linearity

Elliptical cup cross-section

Aerodynamic stability in all-weather and throughout the complete wind speed range is a result of the elliptical cup cross section. Elliptical cup cross section is a very stable aerodynamic shape.

Benefits

  • High full-scale linearity throughout the whole wind speed range

  • Rain and dirt buildup on cups have minimal influence on measurement stability

  • Flat elliptic cups reduce ability for snow buildup on anemometer cups

  • Superb off-axis response for reliable data in turbulent environments


WIND VANE & SAFETY FEATURES

All metal wind direction vane

Efficient all metal design with superb response rate and good aerodynamic damping to prevent overshoots and reduce wind data noise. Held in place by two oversize stainless steel ball bearings for robustness and dirt resistance.

Benefits

  • Fast response and low rotational inertia

  • Low starting wind speed <0.2 m/s

  • Long-term dirt, dust and sand resistance created by the use of two oversize bearings for long-term measurement stability and strength

  • All-metal construction for strength and long life

Lightning protection

2-stage lightning protection against over-voltage, over-current, high speed voltage & current transients, and reverse polarity gives MeteoWind Compact electrical reliability.

Lightning protection meets the following international standards for industrial equipment safety: 

  • EMC Emissions according to EN50081-1 / IEC61000-6-1

  • EMI Transients according to EN50081-1 / IEC61000-6-2

  • ESD 4000 V (4 kV)


OVERVIEW & TECHNICAL FEATURES

 

Combined sensor advantage

  • Two instruments for the price of one

  • Lower power requirements than two separate instruments

  • One sensor, one mount - simpler than two mounts for two sensors (anemometer & wind vane)

  • Less cable, less connections & less electronics equals higher reliability

Accurate measurement

  • Very low starting speed (< 0.2 m/s)

  • Good full-scale linearity

  • Very low distance constant (< 1.5 m) with minimal over-speeding

Technical features

  • Rugged all-metal anodized aluminum housing and wind vane

  • Tough fiber reinforced cups from FRP material

  • Corrosion resistant anodized aluminum body

  • Versatile analog sensor communication interface:

    • Pulse wind speed output (reed switch)

    • Analog protected 0…2.5V voltage output for wind direction.

MeteoWind Compact offers reduced cost of ownership and reliability compared to separate wind vane & anemometer installations for long-term economic benefits for industrial and AWOS weather station operators.
