The form of Anemometer generally used in coal mining consists of a metal ring within which is set a rotating propeller of blade. The air current striking the inclined blades rotates the bane, the number of revolutions being recorded on the face of the dial by means of a series of gears. The instrument is employed to measure the velocity of the air current in mine airways as expressed in feet
