Trident Style 3 Water Meter

Description
This is a disc water meter that fit a 2” pipe, and that was made by the Neptune Meter Company in Long Island City, New York. The Trident was based on designs patented by John Thomson, a prolific inventor and member of the American Society of Civil Engineers. In 1907, Neptune described the Style 3 as the “only meter that can be adjusted for different pressures.” Later trade literature noted that this model was designed for intermediate use, between “the usual house service, requiring but a small volume at moderate rates of flow and that of a manufacturing plant or similar service requiring a larger flow of water.”
