RE: GAS Usage Monitoring ?

["Stuart Billinghurst" <stuart@xxxxxxxxxxxxxxxxx>]

I've seen somewhere a way of doing it by measuring the temperature of
the
bottle, but Google isn't giving me anything useful other than to determine
that a bottle is empty (by which time it's too late)

If you don't want to add a meter how about a set of scales under the
bottle(s). A fairly crude idea, but it how I manually work out when the BBQ
gas is nearly empty.

Apologies for jumping into this thread with a related question,

but how would people go about the same gas monitoring question if you
were on bottled gas? i.e. there is no meter to start from?
