meaning of constants painted inside home electric meter

[Dan Jacobson]

More questions about numbers painted inside my home electric meter
[that bounced when sent to dd-ah-le]:
What does "FM2S" mean?
What does "1 (|) 3W" mean? The (|) is a circle with a vertical line
thru it, a Greek letter, perhaps.
The meter is "Type I-70-S"(any special significance of those numbers?)
made by Chunghsing Co.

What does "FM2S" mean?

FM2S means Form 2S - this is just one of a number of standardized styles of
electric meters for use on various electrical services (Form 2 is for
singlephase 3-wire application). The S means the meter is a detachable
version that plugs into a socket assembly - the other option is A for
"A-base" which has a built-in terminal block on the base (A-base meters are
largely obsolete in North America but standard in the rest of the world).

That just means 'singlephase 3-wire' - the type of service the meter is
built for. that symbol is commonly used in the electric utility industry for
the word 'phase'.

This is the model number of the meter

HUH??? Are you sure it says that and not GE or GE/IUSA? I say that because
the singlephase model now being made by GE is the I-70-S...
