Hi.

Any decent wattmeter does have three connectors, as both current and voltage has to be known for power measurement.

The other meter i think is a angle meter (doesn't really know the english term for this) and that too have to meassure both voltage and current to get a reading.

Thank you, Grossel.

Perhaps, you are referring to a power factor meter?

The arrow thingy appears to be a power factor meter based on the text.

The W is a Wattmeter and since it needs V and I, both are shown. Ditto for the arrow thing.

The squiggle is labeled a Reactor, possibly a saturable reactor or basically an inductor.
