  • The characteristics of pedestrian level winds and how these characteristics affect the choice of instrumentation for measuring wind speed in wind tunnel models are discussed. Hot-wire and hot-film anemometer methods are reviewed. This is followed by a description of a recently developed omnidirectional pressor device for measuring the speed and then by a discussion of some of the less commonly used methods. In the discussions the characteristics of the speed measuring system that are desirable for routine use are outlined. The importance is emphasized of carrying out flow visualization studies to complement the quantitative measurements of speed. (A)
