It would seem that you do not have an "output" from your probes. =
instead,
the gauge reads the resistance of the probe just like an ohmmeter would- =
the
gauge sends power to the probe, and the probe creates variable =
resistance
that is read by the gauge- this is the way that most probes work- =
depending
on what type of digital gauge you have, you should be able to calibrate =
it
to read the probe that you have from skysports. the gauge just needs to =
know
what the range is on your probe to be able to tell you that say 1 ohm is =
a
full tank, and 89 ohms is an empty tank.

That is certainly one possibility.  Since it is described as a =
'capacitance'
probe, it seemed most likely that the circuitry in the probe 'head' =
would
include some kind of oscillator circuit, and then the easiest output =
would
be a voltage.  So I figured Scott B was on the right track.  After 2 =
more
phone calls and an e-mail, I got an e-mail that says the output is a
current.  Apparently the matching gauge is an ohmmeter.  But in spite of =
my
repeated requests for "range" of the output; no such info was =
forthcoming.
It seems the only way I'll ever know is by doing the measurement.

 Oh - but I was told that I could buy a replacement that puts out 0-5 =
volts.
