  • The C3—an alternative anemometer for resource assessment

    Executive Summary. Second Wind Inc. is pleased to offer a new standard anemometer for resource assessment that incorporates industry proven geometry and features. The new three-cup anemometer, the Second Wind Model C3, is physically similar to a popular anemometer designed by Maximum, Inc. and used in the wind industry for more than 30 years. However, the C3 employs more durable materials ...


  • Comparisons of models with data: effects of averaging time as indicated by sonic anemometer measurements

    For continuous sources, plots of predicted against observed gas concentrations often display considerable scatter. These differences are apparent even when the averaging times for the models and data match. Possible sources of error in the observations are shifts in direction of the mean wind or disturbance by intermediate- and large-scale eddies. Errors in predictions may arise from 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 ...

  • 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 ...

  • How much wind is needed to power a home turbine?

    First do you have what it takes? Whether you are considering a small rooftop unit or a large residential turbine you need to know how much wind power is in your area. Wind resource maps, published by the US Department of Energy show airflow speeds at 50 meters (150 feet) above the ground and are a great resource in deciding if you are in a viable location. That's great if you are installing a ...

  • 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 ...

  • Weather Data for Noise Monitoring

    “Weather conditions are the single largest variable factor in how sound travels over large distances,” says Steve Bilawchuk principal partner and engineer at ACI Acoustical Consultants Inc. “Wind speed and wind direction are of crucial importance.” ACI is an acoustical engineering consulting company based in Alberta, Canada, which uses ...

  • 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? ...

  • 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 ...


  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • Weather claims and wind safety

    Anybody working in the construction industry either here in the UK or anywhere else in the world is likely to know that the weather can present us with particular hazards. While rain, ice and snow are particularly dangerous to work in, we must always be aware that the wind is also likely to make conditions unsafe, particularly for those who work at height and those who ...
