FWIW, all voltmeters are ammeters anyway.....Just a matter of the display and the shunt ciruitry.

The only ammeter I can think of, that is not a voltmeter of some type, is the old ammeters with the loop in the back, were you run the current carrying wire through the loop, and the ammeter picks up the field around the wire caused by the current flow. This possibly too could be considered some type of voltmeter, but that would be getting way over my head.

The "old" ampmeter Franklin described is a Tong meter or sometimes called an amprobe. The are very useful and can be bought "new" as I purchased one a couple of years ago. they rely upon magnet field around a wire with current running thru it for measurement.
