Current Meter Register

Usage conditions apply
In 1887, an American hydraulic engineer named Clemens Herschel described a water meter based the principle that the Italian engineer, Giovanni Battista Venturi, had articulated in the 1790s. Examples of Herschel’s meter made by the Builders Iron Foundry in Providence, R.I., were soon installed in numerous large water-works systems. Many were equipped with a mechanical registering device developed by Frederick Connet, the chief engineer of that organization, and his colleague, Walter W. Jackson.
This early example of Connet’s register is marked “VENTURI METER MANUFACTURED BY BUILDERS IRON FOUNDRY, PROVIDENCE, R. I.” A successor firm, Builders-Providence, Inc., donated it to the Smithsonian in 1957. It measures 68 inches high, 22 inches wide, 20 inches deep, and weighs 200 pounds.
In 1899, in recognition of their achievements in this regard, the Franklin Institute awarded the Elliott-Cresson gold medal to Herschel, and the John Scott legacy premium and medal to Connet and Jackson.
