Tropic Model A Water Meter

This is a disc water meter with split case and serial number 2,827,581 that fit a ⅝” pipe. The Pittsburgh Equitable Meter Company introduced the Tropic meter around 1924, for use in areas where water did not normally freeze. The Model A was said to “meet the requirements of the most exacting user, as to accuracy, durability and low maintenance cost” and its materials were selected to resist corrosion.
