This website was established as a reference to the various electromechanical and early electronic meters manufactured in North America. For a list of current meter manufacturers and resellers visit our links page. If you have general questions about meters, or are a fellow meter collector, I encourage you to stop by the meter forum.

An overall historical timeline of meters in the USA can be seen here. For more information view our History of Electric Metering presentation.

If you'd like to talk about meters or have a question, there is now a forum.
