There are 2 types of meters. Electro mechanical and Solid state.That meter is an electro mechanical meter. The aluminum disc uses 2 two coils. One coil is for magnetic flux for voltage and the other for magnetic flux for current. The field of the voltage coil is delayed by 90 degrees using a lag coil. It doesn't sense one leg from the other. The calculation of the watts is still over both legs.
I guess they could monitor both legs, but why would they for a house. As far as Im concerned each county should have their own power plant and off the national grid. Except for Georgia! Much more secure and efficient in my opinion. Even the internet should be put on power lines for more than one reason. Speed being the main reason.
