Can the MeteoWind Compact turn the professional Wind Energy sensor market on its head?

MeteoWind Compact anemometer meets measnet quality of measurement affordably.

MeteoWind Compact anemometer meets measnet quality of measurement affordably.

With the launch of its latest iteration of the elliptic cup anemometer, the MeteoWind Compact, BARANI DESIGN Technologies is poised to make another dent in the wind energy sensor market as dominated by Thies Clima, NRG, and Vector Instruments.

MeteoWind Compact shares the proven robust cup design of its big brother MeteoWind 2, thereby simplifying field service. It is the elliptic cup design which ensures MEASNET linearity [2] (Sample MEASNET calibration report) and enables MeteoWind anemometers to excel not only in precision wind measurement for wind resource assessment but to also offer superb snow shedding for winter operation. A heated version of MeteoWind Compact is also available.

  • As a direct replacement for NRG anemometers, the MeteoWind Compact offers higher precision, requires less hardware to install since it offers wind speed and wind direction measurement in one compact device and is available at a better price point.

  • As an alternative to ultrasonic anemometers, MeteoWind Compact offers higher precision and data reliability in bad weather and in winter. It is also bird damage resistant which is a major cause of ultrasonic anemometer failure. Every year, up to 30% of ultrasonic anemometers are damaged by birds biting out their sound producing ultrasonic transducers. [1]

  • Compared to Thies 1st Class and Vector Instruments anemometers, it offers comparable if not better Class 1 precision and accuracy despite not yet having the MEASNET/IEC 61400-12-1:2017 EDITION 2.0 certification. Additionally, it also offers combined wind speed and wind direction measurement in one device, thereby simplifying installation.

For meteorological applications, MeteoWind Compact offers significantly greater accuracy as required by the WMO and NWS [3], thereby making the anemometers maintenance free for many years after installation.

Innovative spiral design of the MeteoShield Professional begins sea trials on buoys

Marine buoy radiative heating errors to be prevented by the helical MeteoShield Professional.

Marine buoy radiative heating errors to be prevented by the helical MeteoShield Professional.

MeteoShield® Professional begun sea borne testing on marine buoys in the Asia Pacific region last week. Compared to existing multi-plate solar radiation shield technologies and even fan-aspirated shields, it offers a significant improvement in all weather precision for air temperature and air humidity measurement. Compared to fan-aspirated shields, it has the added benefit of superior reliability.

This advantage in measurement precision is hoped to make a significant contribution to the quality of climatological measurements and is poised to increase confidence and precision in quantifying global warming and its associated climatic changes to the region.

Has Rainwise resorted to false claims instead of innovation in the IoT personal weather station market?

MeteoHelix may be the first true IoT weather station

MeteoHelix may be the first true IoT weather station

It’s a sad day when past innovators resort to false claims instead of innovation. Five months after Rainwise contacted BARANI DESIGN Technologies about the MeteoHelix® IoT Pro personal weather station, did Rainwise make a claim to be the 1st IoT weather station on the market.

The MeteoHelix IoT Pro personal weather station begun sampling to customers in the spring of 2018 as a year long testing campaign begun. Almost a year later, Rainwise begun announcing “the world’s first compact, solar powered, commercial grade, true IoT MK4 Weather Station.” with pre-orders of 6000 plus units. A few months later announcements that the not yet released MK4 “IoT weather station has already secured purchase commitments of over 7,000 units in 2019 without the product being officially released” are being claimed on the website in the Rainwise company description.

USA is known for innovations

USA is known for innovation and the MeteoHelix® is proof of that. While we believe that no one can claim to have the first IoT weather station, the MeteoHelix IoT Pro brings a number of firsts to the market. Its ability to measure at World Meteorological Organization (WMO) and National Weather Service (NWS) precision standards for under $600 is unprecedented in the professional meteorological world and the personal weather station marketplace.

Proof of its pedigree can be found in WMO research papers like the RMI comparisons where its innovative helical shape proved to surpass the precision of professional meteorological networks monitoring climate change. Neither Davis nor Rainwise weather stations can claim to provide the professional meteorological data quality of the MeteoHelix even with their fan-aspirated counterparts.

While the MeteoHelix® is currently manufactured in Slovakia, its roots and inventor are “Made in USA.” RPI educated and groomed at Boeing, the MeteoHelix’s roots share this pedigree. Plans are in the works to bring the MeteoHelix personal weather station production back to the US. A self-cleaning rain gauge is also in the works. Please stay tuned and enjoy the view.
