Arctic Model A Water Meter

This is a disc water meter with frost-proof bottom and serial number 1,571,523. It fit a ⅝” pipe. The Pittsburgh Equitable Meter Company declared that it “will meet the requirements of the most exacting user, as to accuracy, durability and low maintenance cost.” It was “equipped with a bronze upper case and a cast iron breakable bottom plate, amply heavy and strong enough to withstand pressure far in excess of that encountered under ordinary service conditions, but designed to break when exposed to excessive strain imposed by freezing.” “Only materials that pass our strict laboratory tests, and comply with our rigid specifications are used in its construction, and the most skilled workmen employed in machining, assembling and proving.”
