Nash Water Meter

This is a disc water meter with frost-proof flanges on the bottom and serial number 2,060,039 that fit a ⅝” pipe, and that was made by the National Meter Company in Brooklyn, New York, probably in the 1930s. The name refers to Lewis H. Nash, the man who served as chief engineer of National Meter for over thirty-five years and who, in the late 1880s, designed the first disc meter made in the United States.
National Meter began in business in Manhattan in 1870, broke ground for a larger factory in Brooklyn in 1891, and announced in 1893 that it was “the largest establishment for the manufacture of water meters in the world.” It became the National Meter Division of the Pittsburgh Equitable Meter Company in the early 1940s. National Meter and Pittsburgh Equitable Meter became divisions of the Rockwell Manufacturing Company in 1947; and Rockwell became part of SENSUS in 2003.
