I don't know if the OPD gadget prevents the tank from
dispensing liquid if the tank is upside down. One of the
great learning moments of the world.

i think it may be more complicated..

the tank is filled partly with liquid and partly with vapor. the
connection is set up to let out only the vapor. in fact I think if
you turn the tank upside down to try to flow fluid out, there is a
valve that closes to prevent the flow of liquid. when you go to a
refill place, they have a special setup to flow liquid. If you are
going to transfer by vapor only (by cooling the destination tank), it
will take a long time to transfer a significant amount..

but I am only guessing at this, i could be wrong, anybody know for
sure?
I'd also like to know a good way to transfer propane...
