Fteley-Stearns Water Current Meter

Description
Alphonse Fteley was a French engineer who came to the United States in 1865. In 1873 he took charge of the Sudbury River Waterworks that would bring potable water from the Sudbury River to customers in Boston. To gauge the water flow in the Sudbury River, he borrowed a Baumgarten current meter from General Theodore G. Ellis. Then, working with Buff & Berger, a mathematical instrument firm in Boston, Fteley and his assistant, Frederick P. Stearns, devised a meter with a larger rotor, eight blades with a longer pitch, and a different mechanism for the counting wheels.
Buff & Berger was offering Fteley-Stearns direct-reading current meters by the early 1880s. Following the dissolution of that firm in 1898, instruments of this sort could be had from Buff & Buff and from C. L. Berger & Sons. A Fteley-Stearns meter with ordinary registering apparatus cost $160 in 1899. The same, with an electric register, cost $220.
This example is marked “C. L. Berger & Sons / Boston, U.S.A. / 5969.” The additional “U.S.G.S. / 781 / HYDRO” mark indicates that it was used by the Hydrologic Department of the U.S. Geological Survey. Arthur Frazier donated it to the Smithsonian in 1970.
