Would it work to weigh the tank with the whip connected?  You'd have to
allow for the weight of gas in the whip (or make sure you both start and
end with the whip either pressurized or depressurized, or determine that
this weight was insignificant) and make sure the whip was hanging free so
that it wouldn't upset the weight.

Possible procedure: put tank on scale, attach whip, open supply valve to
pressurize it, zero the scale, open the tank valve, fill to desired weight,
then close valves and drain the whip.

This would sort of rule out doing good fills on a boat; wanting to be able
to do that would be a good argument toward putting the money into a good
gauge instead of a scale anyway.
