  • What are the advantages of ultrasonic wind sensors?

    Whether mechanical, ultrasonic or laser wind measurements: All measuring methods have technical limits. While for mechanical wind sensors the measuring element – cups and vanes – itself predominantly produces a disturbance in the flow field, for ultrasonic anemometers a disturbance can be caused by the sensor holder or housing construction. Only optical methods, e.g. LDA (Laser ...

  • How a Lufft sensor helps to improve a solar car

    After a successful collaboration between Lufft and the Punch Powertrain Solar Team in the Bridgestone World Solar Challenge of 2013 and 2017 (6th and 3rd place), both parties decided to extend the partnership. The World Solar Challenge is a race of 3020km straight through the ...

  • Lufft sensors now officially approved for airports in Ukraine

    Background info There are 16 international civil airports in Ukraine. At the moment only 10 of them are in operation. A major modernization and restoration program for airports is currently underway in the country. This includes the construction of new runways and the reorganization of aviation weather services. In this context, all existing AWOS (Automated Airport Weather ...

  • Lufft WS200 wind sensors on a research station in the Antarctica - Case Study

    Base Orcadas is an Argentine scientific research station in the Antarctica. It is located on Laurie Island, one of the South Orkney Islands (Spanish: Islas Orcadas del Sur), at 4 meters (13.1 ft) above sea level and 170 meters (558 ft) from the coastline and is the oldest one there which is still in operation. The nearest port is the Argentine city of Ushuaia, which is 1,502 km (933 mi) away. ...

  • Lufft weather sensors are used where others failed

    The ski lift in Visperterminen Rothorli leads from the village through pinewoods to the 2300m high winter sports region. On August 15, 2018 a Lufft WS600 weather station was installed and put into operation. Its main task is to provide the lift staff and piste team with climate data in winter. The data ...

  • Weather monitoring network equipped with Lufft wind sensor VENTUS - Case Study

    In 2010 we won a tender for 30 ultrasonic anemometers (as a part of meteorological weather stations). The National Weather Service of Mexico (CONAGUA) wanted to build weather stations in the southwest of Mexico (States of Chiapas and Tabasco). According to the customer, Ventus-UMB is a very robust, yet precise sensor with a very good price / performance ratio. Moreover, data transmission via ...

  • Basic tests for checking validity of field data

    The following guidelines are suggested for verifying micrometeorological data gathered in field experiments. It is assumed, for simplicity, that the observations being tested are made over open, relatively flat and uniform terrain, with small roughness elements. It is also assumed that the sensors and the data acquisition and recording hardware are basically sound and that the purpose of the ...

  • Industrial thermal mass flow meters Pt.1 -Pt.2 - measurement & control

    An industrial thermal mass flowmeter measures either the mass velocity at a point in a flowing gas or the total mass flow rate through a channel or pipe. Figure 1 shows a typical thermal mass flow sensing element. It consists of two sensors: a mass flow sensor and a temperature sensor, which automatically corrects for changes in gas temperature. Both sensors are reference- grade platinum ...

  • Weather measurement in extreme conditions - Whistler Mountain - Case Study

    Whistler Blackcomb mountain is a premiere winter resort in British Columbia Canada. Some months ago our subsidiary "LufftUSA" installed the first Ventus-UMB ultrasonic anemometer atop a main ski lift on the Whistler mountain. The first winter storm passed leaving the entire mountain and all mechanical equipment covered in snow and ice... except the Ventus-UMB. The Ventus-UMB continued to give ...

  • A preliminary analysis of measurements from a near-field pollutants dispersion campaign in a stratified surface layer

    In order to study pollutants dispersion in a stably stratified surface layer at small scales, a pollutants dispersion field experiment programme is being conducted on the site SIRTA in the southern suburb of Paris. In a preliminary campaign held during the winter of 2012 with continuous gas releases, we had 12 ultrasonic anemometers measuring wind velocity and temperature at 10 Hz, and six ...

  • On the wind flow patterns under neutral and unstable conditions in an urban area

    Wind flow and pollutant dispersion within urban areas depend on the approaching flow profile and temperature stratification. Thus, the flow field developed under neutral and unstable stratification conditions, within a street–canyon, was studied experimentally and numerically for a two–dimensional urban background set–up. Wind–tunnel measurements were carried out with a triple hot sensor ...
