Empire Magnoseal Water Meter

This is an oscillating piston water meter with a frost-proof bottom and serial numbers 912,409 (on the lid) and 912,413 (on the side). It fit a ⅝” pipe, and was made by the National Meter Company in Brooklyn, N. Y. The Magnoseal, introduced in 1912, was apparently a magnetic drive designed to eliminate the stuffing box, a device that prevents leakage along a moving part passing through a hole in a vessel containing steam, water or oil.
