Patent attributes
A fluid flux measurement system that includes a heated element fluid flow sensor that is capable of being repositioned relative to a mean fluid flux direction is disclosed. The repositioning may be performed by a motor interconnected to the heated element fluid flow sensor. The heated element fluid flow sensor may be positioned proximate to the measurement region of a sonic anemometer and may be operable to be repositioned relative to the sonic anemometer. The heated element fluid flow sensor may be a three-dimensional hot-film constant temperature anemometer. The fluid flux system may be operable to measure small-scale turbulent fluxes in uncontrolled environments such as remotely located atmospheric monitoring stations. The heated element fluid flow sensor may be calibrated in-situ with data collected by the sonic anemometer.
