  • Technology white paper: immersible thermal dispersion

    Thermal dispersion mass flowmeters comprise a family of instruments for the measurement of the total mass flow rate of a fluid, primarily gases, flowing through closed conduits. The operation of thermal dispersion mass flowmeters is attributed to L.V. King who, in 1914 (Ref. 1). published his famous King's Law revealing how a heated wire immersed in a fluid flow measures the mass velocity at a ...

  • Momentum Flux: Gross, Scalar, Alongwind, or Net?

    Modern micrometeorology is an amalgam of two traditions: one arises from field measurements in the open atmosphere and another from wind tunnel experiments. Early micrometeorological field work, and even relatively recent studies (viz. the von Karman constant experiments by Frenzen and Vogel, 1995), were done with precision cup anemometers, which can only provide a scalar speed measurement. Most ...

  • How to Keep Your SymphoniePRO Data Secure

    Data matters. The accuracy, consistency, and yes, safety of measurement data keep many wind developers and analysts up at night. Customers often ask about the digital and physical security of RNRG instruments, so I sat down with Michael Fisher, product manager for our wind resource assessment (WRA) line, to get answers to the most common questions. Q: Why is data security important? ...

  • Future inside – smart environmental sensing technology

    SHM30 snow depth sensor in Antarctica (photo: Alfred-Wegener-Institut, Helmholtz-Zentrum Bremerhaven) A lot of sensing technologies have changed recently: Ultrasonic wind measurement replaces cups and vane systems, closed anemometer designs offer better protection from ...

  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...
