On my system, there's a 50 ohm cable from the transceiver to
the input of the SWR meter and another 50 ohm cable from the
output of the SWR meter to the balun. Each of these cables
forces the ratio of the voltage to current in each of the
traveling waves to a value of 50 ohms. I have an in-line
Autek WM-1 and no tuner.

Cec,
You can't measure SWR on a line which is less than 1/4-wave long.
Preferably it should be as long as 1/2-wavelength to ensure the max
and min voltage points both occur on it.

But what do you do with the SWR when you have measured it? Of what use
it?

All anybody needs to know is whether the transmitter is terminated or
is not terminated with 50-ohms. This is very important.

And when describing to a novice how your station works there's no need
to mention SWR or reflections. They are quite unecessary complications
and can be dispensed with except perhaps for trolling on newsgroups.
