ASW-20 Mystery Instrument

[jcarlyle]

I was helping a friend with his ASW-20, and we took a mystery
instrument out.

The instrument consists of a small project box containing a single
layered printed circuit board, non-silk-screened, that holds 3
integrated circuits, a few resistor packs, a few capacitors and a 20K
trim pot. Etched onto the board are the initials KLC and WLSE2A. There
are power and ground leads coming in, leads going out to a 0 to 1.0 mA
meter that was mounted at the bottom of the panel, and a DB9 jack
bringing in 7 signals from a cable that goes back to the tail. There's
nothing obvious that we can see in the tail.

Anyone have any ideas as to what this instrument might have been used
for?

The system you describe is a tail tank water level measurement system
and indicator.

Designed and fabricated by Kevin Cousineau (KLC) and probably
installed at Glass Teck in Tehachapi by Rick Wagner and/or myself in
conjunction with a tail tank install.

Thanks for identifying it, Mark.
