A Preliminary Test of an Anti-Freezing Combination Wind Vane and Anemometer on the Summit of Mt. Fuji

Abstract

A Speedovane (an experi m ental combination wind vane and anemometer) is fitted with electric heaters and tested for about ten days in March 1953 on the summit of Mt. Fuji (Station height,3,773 m above sea level). From the test the total heater capacity of 650±70 watts is found sufficient for the anti-freezing purpose in ordinary icing conditions.
