- Sangamo Electric Company Gutmann Type B Wattmeter, 1901-1903 - In the late 1800s, companies that supplied electricity to consumers needed a way to measure how much customers used -- and then charge them accordingly.

- Sangamo Electric Company D-5 Wattmeter, circa 1914 - In the late 1800s, companies that supplied electricity to consumers needed a way to measure how much customers used--and then charge them accordingly. Induction-type wattmeters proved reliable and would become the industry standard, but until 1910 Westinghouse held the patents. Sangamo Electric Company, which had not been granted a patent license, produced a mercury-motor alternative. This version was made well in the 20th century.
