MeteoWind Compact and MeteoWind IoT Pro ICE-FREE update

MeteoWind Compact2 anemometer update at the Meteorological Technology world Expo 2024.

Introducing the 2025 update of the MeteoWind Compact—now on sale! This highly anticipated upgrade to one of the meteorological industry's most reliable and accurate anemometers features a sleek, more aerodynamic body and a new black ICE-FREE wind vane makes for easy differentiation. While it retains full interchangeability with its predecessor, its name now includes a squared symbol, distinguishing it as the next generation of excellence.

New for 2025

MeteoWind Compact²

• New black wind vane made of stainless steel reinforced plastic

  • Improved wind vane response and damping

    • Wind vane Delay distance < 1.0 m (acc. to ASTM D 536696)

    • Wind vane Damping ratio D = 0.31 (acc. to ASTM D 536696)

    • Wind vane Starting threshold <0.1 m/s at 90° amplitude (acc. to VDI 3786 Part 2)

  • Enhanced ICE-FREE winter operation even without heating. - a heated version of MeteoWind Compact² will be available in early 2025

• Solid-state wind speed sensor with enhanced vibration resistance and reliability

  • New solid-state sensor technology to measure wind speed (replaces reed switch)

  • Redesign of its aerodynamic body to enhance linearity and accuracy beyond the most stringent MEASNET/WMO/EPA requirements.

• More robust mounting bracket and more user-friendly mounting

• Enhanced MTBF (Mean Time Between Failures) is 987,090 hours (112 years) per MIL-SPEC: MIL-HDBK-217 F Notice 2 Parts Count section ANSI/VITA 51.1-2013 (R2018)

• Enhanced winter operation for wireless weather stations that do not have enough power to heat wind sensors

• ICAO approved for all-weather airport use

Hand-held MeteoWind® - the most precise hand held anemometer on the market to date

Hand-held anemometer during a storm chase

Hand-held MeteoWind® has been designed to fill the need of our customers for a robust and mainly precise anemometer for on-site wind speed measurement. Designed for construction workers, storm chasers, crop dusters, farm sprayers and HVAC applications, it features very low starting speeds of <0.3 m/s (<1 ft/s) and offers a Bluetooth interface and a sealed USB charging port. Anodized aluminum body makes it durable and chemical resistant.

For more information, please contact BARANI DESIGN Technologies s.r.o. or COMPTUS Inc. of USA for hand held anemometer availability.

Why did MEASNET/IEC 61400-12-1:2017 EDITION 2.0 ignore anemometers with direction vanes?

In 2017, when MEASNET/61400-12-1 Edition 2.0 was approved, the Elliptic Anemometer had been around for at least 4 years and MeteoWind® 2 for at least a year and both were excelling and passing MEASNET linearity requirements at MEASNET's favorite wind tunnel, Deutsche WindGuard GmbH.  Why did MEASNET choose to ignore these wind speed and direction sensors in their Edition 2.0 update?

Arguably, data quality from a wind sensor that measures wind speed and direction together at a single point like MeteoWind® 2 is of higher quality than that from separate wind speed and direction sensors connected by tubes and separated by trusses of lattice towers, as is the status quo with current First Class or Class 1 anemometers. 

MeteoWind® 2 MEASNET calibrated anemometer

Outdated MEASNET mounting requirements of anemometers and wind vanes on lattice towers for wind energy assessment state that the wind vane must be at least 1.5 away from the anemometer.

Does this mean that IEC 61400-12-1: 2017 Edition 2.0 is already outdated at the time of publishing since it did not take into account existing technologies? Is MeteoWind® 2 an exception? Since it is a single instrument, the 1.5 meter rule does not apply.
