Birds’ fight against ultrasonic wind sensors

Ultrasound and wildlife reserves

Ultrasonic anemometers seemed like the solution for maintenance-free wind measurement, yet nature had its say. Their ultrasound, while being inaudible to humans, is disturbing enough to natural wild life so that each year, birds destroy about 1/3 of all ultrasonic sensors by biting out their ultrasonic transducers as reported by the German Met Office. [1] This leads to the question of whether ultrasonic sensors are environmentally friendly and whether they should be allowed in wildlife reserves and national parks or if their application should be limited to industrial use?

Cup anemometer renaissance

New advances in electronics and manufacturing are enabling mechanical cup anemometers to not only outlast their ultrasonic counterparts but to maintain their accuracy advantage and to remain the mainstay of meteorological measurement and of the precision wind energy industry.

Strategic Partnership of BARANI DESIGN Technologies and Comptus Inc. of USA

BARANI DESIGN Technologies and Comptus Inc. of USA strategic partnership announced.

BARANI DESIGN Technologies and Comptus Inc. of USA strategic partnership announced.

BARANI DESIGN Technologies of Slovakia (formerly Czechoslovakia), will create a strategic partnership with Comptus Inc. of USA, who is one of the only two producers of the most widely used anemometer for wind energy applications worldwide. The immediate benefits of this partnership will include:

In a technology sharing program, both companies will join forces to develop a low-cost wireless precision wind measurement solution to complement the MeteoHelix IoT Pro wireless weather stations and to directly compete in the high-end and middle market segments in agricultural weather station applications. The MeteoHelix and MeteoWind Compact combination will become the only affordably priced weather station solution to meet the Wold Meteorological Organization (WMO) measurement standards. This meteorological sensor solution is aimed at putting precision back into precision agriculture which is currently being dominated by measurement equipment not conforming to worldwide measurement standards.

New product launch preview for the Meteorological Technology World Expo in October 2018

The 2018 show will launch MeteoWind Compact anemometer, ezMETAR weather stations and MeteoHelix research-grade micro-weather stations based on the award-winning helical MeteoShield Pro design.

The inventor of the helical radiation shield will be presenting and explaining the principles behind this innovative helical weather station. After over 12 years of research and 10 years of field experience, MeteoHelix weather stations based on the patented design of the helical solar shield, allow previously difficult-to-achieve measurement accuracy, precision and reliability in an economical all-in-one weather station. These solar powered and wireless all-in-one weather stations are able to remain operational for 6+ months without sunlight and can use satellite data uplinks for meteorological data with satellite LoRaWAN gateways.

BARANI DESIGN Technologies will be exhibiting the helical MeteoShield Professional, MeteoHelix and professional AWOS weather stations in booth 10005 at the Meteorological Technology World Expo on 09-11 October 2018 in Hall 8, Amsterdam RAI, in the Netherlands.
