Fort Wayne Duncan Wattmeter, 1896-1899
01
Artifact Overview
In the late 1800s, companies that supplied electricity to consumers needed a way to measure how much customers used--and then charge them accordingly. Thomas Duncan developed wattmeters for several companies before starting his own meter manufacturing business in 1901. This induction-type wattmeter was developed for the Fort Wayne Electric Works in the late 1890s.
