An approximation to the former type of body is found in the cup of the meteorologist's anemometer.
These perturbation data were used to evaluate the coefficients in a curve-fit of the flow velocity to the anemometer output voltage.
An electrostatic filter was placed at the entrance to eliminate dust contamination of the hot-wire anemometers.
Such an assumption cannot be checked with present data because the span of the set of anemometers is barely the width of one double-roller eddy.
Each position in the array contains a single-wire hot-wire anemometer probe.
Under this definition, windmills, water wheels, anemometers, and certain tree fruits and seeds are ' autorotating ' devices.
The initial templates used by the pattern recognition algorithms have been obtained by simulating the passage of a double roller over the set of anemometers.
The anemometers are calibrated by means of hot-wire measurements of phase in the periodic heat wake of a fine wire heated from the mains.
