UNIQUE FEATURES & BENEFITS


Compact sensor exceeds  accuracy of MEASNET

DSC02415.jpg

MEASNET linearity and angular response has never been this compact. Elliptic cups allow MeteoWind 2 to shine in all-weather.

Single point wind speed and wind direction data compared to separate anemometer wind vane installations means that wind data quality has never been so good.

Wind speed accuracy and dirt resistance of MeteoWind 2 also permits very long maintenance intervals while meeting WMO requirements.


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

The positive aerodynamic properties of elliptic cups enabled us to make MeteoWind 2, the most compact anemometer to meet the strict MEASNET linearity requirements.

Strong and durable

Compact and responsive all-metal wind direction vane with superb response rate and good aerodynamic damping prevents overshoots to reduce wind direction data noise. Sitting on oversize ball beatings, the design balances rotational inertia with aerodynamic efficiency resulting in a compact and accurate wind direction vane.

Benefits

  • Fast response matched to anemometer response
  • 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

Aerodynamically stable body

Strong and durable anodized aluminum body creates a robust platform for mounting. Body shape and circumferential grooves contribute to the anemometer's full-scale linearity and accuracy, while a bayonet connector with IP67 rating down to -40 °C provides reliable connections.

Benefits

  • All-metal construction for stability, strength and long product life
  • IP67 connector for winter operation down to -40 °C
  • Compact body allows for a efficient heating of ball bearings and body
  • Body shape and features contribute to the anemometer's MEASNET & WMO accuracy

LIGHTNING PROTECTION


Lightning-Stormchasers_SK.jpg

Advanced lightning protection comes standard

Highest class 3-stage lightning protection consisting of:

  • high-over voltage protection 
  • high speed over-current protection
  • high speed voltage protection

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
  • SURGE test 4 kV / 2 kA acc.to EN50082-2 / IEC61000-6-2
  • ESD 15000 V (15 kV)

The use of 3-stage lightning protection is complemented by the RS-485 digital output which has inherently high resistance to interference and is therefore most widely used communication interface in tough industrial environments. Together, they are able to ground out any unwanted electrical interference from wired connections.


HEATED ANEMOMETER


IMG_2104.JPG

Heated MeteoWind 2 adds body and ball bearing heating to the already robust MeteoWind 2 anemometer with wind vane.

Heater generates a generous 20 W on 24 V or 5 W on 12 V.  For wireless weather stations, the heater includes automatic switching with the following user selectable settings:

  • Heater OFF
  • Heater ON, controlled by temperature
  • Heater ON, controlled by temperature and activates only when wind speed reading is less than 2 m/s. Once activated, heating cycle runs until completed

The photo clearly shows how anemometer heating can benefit data reliability in tough winter climates. While it does not completely eliminate ice buildup on the anemometer cups and wind vane, it significantly reduces the icing effects and prevents the anemometer and vane from completely icing up.
