The translucent body of our Gaslights works quite well, a feature that the Calor-Lite replacement if it ever comes out "reportedly" shares.
So, for many this "need" ought to be sorted in the near future.
I find just loosen the straps and lightly rock the bottle to gently cause the liquid gas surface to move, helps be sure to see where it is.
Someone will retail an expensive "rule" as a plastic clip on strip, to convert the level to kgs for those who need the specifics?

How can what is effectively no more than a pressure gauge really give any hint of the bottles content, other than when the liquid is depleted and the remains of LPG are into the gas stage?
To my mind all it shows is the liquids vapour pressure. This is not contents variable whilst there is still liquid there, only once it is all evaporated and the gas pressure starts falling on useage. It responds to temperature of course of which contents has a secondary effect as a heat sink, but not directly contents.

Picking up automotive LPG outside the UK where Butane in varying amounts is included?
If that is the area of interest here, then when in sustained very cold conditions we are IMO into nightmare territory
The behaviour in leaching of the more volatile Propane part, in our vapour take off systems as opposed to the intended liquid take off automotive case, is hugely complicated.
All this making determining the "effective" contents, ie what contents will gas off, as compared to what is physically there, in these colder ambient, simply as said a nightmare.

Becuase usually my Gaslow propane guage fitted to my change over system has proved quite accurate over the years but has recently been otherwise after a couple of Continental trips which involved filling up with Continental mixes of gas. I got to wondering if the guage was faulty or whether it was due to contents.
Thanks for the responses most useful
