Bailey Meter Co. Square Root Planimeter with Three Cams
Bailey Meter Co.
USA
Unknown
ca. 1930
N/A
Determining fluid flow from circular pressure diagrams
Notes: "This planimeter would have been used much like a radial planimeter on a circular chart, but the chart would be pressure measurements from a pitot tube in a pipe carrying, probably, water. The three interchangeable cams adjust the square root function of the planimeter for different types of charts."
