  • The evolution of thermal mass flow meters

    Who were some of the pioneers in thermal mass flow technology? A. Thermo-Systems, Inc. (TSI) began in its founder’s basement in 1959, with a cooled-film anemometer designed for transient measurements in high temperature fluid flows. This led to TSI’s hot-film and hot-wire anemometers, the first commercial products of this type. These immersion-type devices were used mainly as ...

  • Sonic Thermometry

    Sonic anemometers have had extensive use in the scientific community. These instruments are used to measure atmospheric parameters that most rotating instruments cannot. Wind speed and wind direction or individual axes of wind velocity are most commonly measured. Along with these measurements, another parameter can be extracted from the sonic anemometer (i.e.), sonic temperature. Since the ...

  • 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 ...
