I have also noticed more and more of these devices around town.  And =
they always seem
to be attached to what I believe are gas meters.  They are attached =
usually to a
device with a disk-shaped head about 1' to 2' in diameter.  I think that =
the old
devices had a pen recorder on a circular piece of paper that recorded =
the gas flow
over a period of days or weeks, maybe even months.  Or possibly the gas =
pressure.
This would allow the gas company to detect leaks, overburdened =
distribution systems
causing low pressure, or pressure spikes, all of which could be =
dangerous.  Someone
would probably have to change the paper periodically, a no-no in this =
era of labor
reductions.

Outside of the District, I see a lot of solar panels used to power =
traffic sensors on
the secondary roads of Virginia.  These are usually identifiable by the =
induction
loop in each lane.  I don't know where they report to or on what =
frequency.

Walking around in Annapolis I noticed that many electric meters for =
traffic signals,
street lights, and other "unconventional" or non-consumer uses had a box =
about the
size of a cigar box that had an antenna about 6" long.  It seemed to be =
some sort of
remote reading electric meter, based on stickers.  I don't recall what =
the stickers
said that made me think it was an electric meter at the time, probably =
BG&E. =20

I guess that all of these are SCADA or SCADA-like devices, and that we =
will probably
see lots more of them as labor savings becomes more prevalent and =
wireless devices
more common.  My water meter is read by RF now.

I was told they are Washington Gas devices used to
monitor the natural gas lines in DC.  There's also
one in Adams Morgan at the intersection of Adams Mill
& Lanier.
