A Novel Application of the Polar Planimeter
The steam meter designed by the writer for the use of the New York Steam Company, automatically registers upon a strip of paper, moved longitudinally by clock work, at the rate of ½-inch per hour. A base line is formed upon the paper by a stationary pencil, and a movable pencil operated by the meter traces a diagram, the height of which above the base line at any point is proportioned to the weight of steam flowing through the meter at the corresponding time, less a constant difference in elevation on diagram, due to the lap of the meter valve.
