![]() From ultrasonic wind gauges to hot wire anemometers and doppler wind speed meters, which are often used in weather radar to measure the movement of air. But in the last century, there have appeared some more futuristic wind meters. Over the years, the basic anemometer hasn’t changed all that much. However, the wind vane is still by far the most common device for measuring wind direction. With this addition, the speed of the anemometer moves faster or slower depending on whether the tag is moving with or against the wind, and from this the wind direction can be calculated. This was achieved by adding a tag to one of the wind cups. In 1991, Derek Weston developed the three-cup anemometer even further, by added the ability to measure wind direction as well as wind speed. One of the more notable improvements of the wind meter was the invention of the three-cup wind meter by John Patterson in 1926. Over the centuries, it has been improved by a number of different people. by Italian author and architect Leon Battista Alberti. The first wind gauge was created around 1450 A.D. We’ll go into more detail about each of these later. Nowadays anemometer is still the most commonly used term for referring to a wind speed measuring tool, especially in the scientific field.Īnemometers come in different types: handheld anemometers, digital anemometers, wind gauges part of a more advanced home weather station and more. The word anemometer actually originated from the Greek word “anemos”, which translates to “wind”. Since the word anemometer isn’t the easiest to say or spell, wind speed measuring devices are often referred to as a wind gauge or wind speed meter. Together, they are able to ground out any unwanted electrical interference from wired connections.A Beginner's Guide to Anemometers What is an Anemometer?Īn anemometer is a measurement device that measures wind speed. 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 the most widely used communication interface in tough industrial environments. Link to lightning protection test report: Lightning Protection Certification (EMC test results).SURGE test 4 kV / 2 kA acc.to EN50082-2 / IEC6.EMI Transients according to EN50081-1 / IEC6.EMC Emissions according to EN50081-1 / IEC6.MeteoWind Lightning Protection meets the following international standards for industrial equipment safety: Whats more, MeteoWind 2 has the highest lightning protection currently available consisting of: MeteoWind 2 has a IP67 connector, therefore, cable length can be chosen per customer requirement. Meteo tower and meteo mast cable lengths may differ as the tower heights are variable (i.e. ![]() As you can imagine, if a customer installs 120+60 MeteoWind 2, their data quality, data density, and data redundancy will be significantly higher than with separate installations of wind vanes and anemometer at the same total cost.As logic would suggest, measuring wind speed and wind direction together at a single point creates much more meaningful data which can more accurately quantify turbulence and wind shadow effects of masts and wind turbines.Further, MeteoWind is a single wind sensor measuring wind speed and direction and not two separate instruments as IEC 6 assumes. ![]() This IEC 6 requirement was written before the MeteoWind 2 wind sensors were developed. Does MeteoWind 2-in-1 wind speed & direction sensor satisfy this requirement as they will measure at almost same height. ANEMOMETER FOR SALE INSTALLMoreover we install anemometers and wind vanes at different heights. IEC 6 specifies clearly that no other instrument shall be positioned closer than 1.5 meters vertically from the anemometer cups and the wind vane shall be mounted at a minimum of 1,5 m below the primary anemometer. Our requirement is 120 units of anemometers and 60 units of wind vanes. ![]()
