Advanced thermal dispersion mass flowmeters
Thermal dispersion (TD) mass flowmeters measure the mass flowrate of fluids (primarily gases) flowing through a closed conduit, such as a pipe. This article describes the operation and installation of TD mass flowmeters, and gives the reader information about what applications these meters are most suited for. Background The first general description of TD mass flowmeters is attributed to L.V. ...
A new paradigm for thermal dispersion mass flowmeters
Since the publication of the American Society of Mechanical Engineers (ASME) standard on thermal dispersion mass flowmeters in 2011, there have been major advancements in the technology. A review of ...
Tsunami forecast models `too simple`, say researchers
Tsunami forecasting could be significantly improved if the computer models used to predict wave behaviour were to incorporate data on the waves' complex behaviour as they come into shore and break, according to researchers. Writing in a themed ...

Smart Laser Doppler Velocimeter (LDV)
A Laser Doppler Velocimeter (LDV) measures fluid velocity by utilizing coherence of laser light. It detects the Doppler shift frequency of the scattering light of particles in the fluid and calculates the velocity of the particles (fluid). With a LDV system, non-intrusive measurements without disturbing the measuring object, liquid or gas flow, are achieved. No calibration is necessary and ...
