Watch Dog Water Meter

This disc water meter, with split case and serial number 18,536, was made by the Gamon Meter Company in Newark, New Jersey, in 1910 or shortly thereafter. Ernest E. Gamon, Jr. resigned his position as factory manager of Neptune Meter in 1909, opened a new firm in Newark, and showed a Watch Dog meter at the annual meeting of the New England Water Works Association. By 1915 he was boasting that Watch Dogs were in use on over 90,000 taps throughout the country.
