Nash Type 9-AX Water Meter

This is a disc water meter with frost-proof flanges on the bottom, that fit a ⅝” pipe, and that was made by the National Meter Company in Brooklyn, New York. The serial number has been obliterated. 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. AX designates a circular register.
