Abstract
With a hope to find a breeze indicator of aerodynamic type three kinds of pendulous-plate anemoters and also three kinds of bridledwindmill anemometers are experimented in the towing water tank without water, at the Meteorological Research Institute. The carriage speed is under 1 m/s, and the anemometer indications are given by the inclination angle of the plate, and the twist angle of the windmill shaft respectively. The results suggest the possibility of the proposed anemometers down to 0.25 m/s or even lower wind speed.
