MeteoWind 2 wind sensor
Wind speed & wind direction
Serviceable bearing & cups with high dirt resistance
Elliptic cup design offers snow resistance and high accuracy per WMO & MEASNET standards
Anemometer with a wind vane. Exceeds WMO and MEASNET Class 1 accuracy standards for meteorology & wind resource assessment. Very low 4mA combined power consumption and integrated triple layer lightning & surge protection for reliable operation. Protected oversize bearings with high dirt and weather resistance proven to provide long-term measurement stability & reliability in dirty & dusty environments.
- Very low starting wind speed for such a compact anemometer
-
Excellent linearity and accuracy exceeding MEASNET requirements
-
Excellent off-axis response. Low distance constant
- Flat elliptic cups are more resistant to snow buildup
