Hi guys,

Do you know how watthour meters work?

I would like to see some schematics of their internal circuitry if you have.

 

The disk spins due to hysteresis currents induced from the surrounding coils. The revolutions turn a gear train, or get counted by circuitry.

Here's the Wikipedia material - http://en.wikipedia.org/wiki/Electricity_meter.
