google propane and read on about its properties. Propanes boiling point is -44.3 f. At that temp there is no pressure at all, you could pour it out and carry it in a bucket. OH ive done that in Ontario at -50 f.
Pressuse gauges are of no use, because at any given temp. they will show the pressure developed by the liquid as it boils to vapor at that temp. So at -43f it would show empty on a full bottle, yet at + 90f show full on an almost empty. .They cannot show the liquid level.
, only float gauges can tell you the liquid level in a bottle. Motor homes have them that show 1/4-1/2 -3/4. Acommon issue with them is that if 80% is full, then they should read more like 1/3-2/3-3/3 which more closely is the liquid level.
The hot or cold water test ( use one or the other depending on the ambient temp- hot weather use ice water, cool weather, hot water) poured down the side of the bottle then run your fingers down the bottle to feel the temp change will show you the liquid level in the bottle, as the water will heat or cool the metal only down to the liquid propane level.
Stick on heat sensative strips are very good at this test.
I have always left both valves open with the switchover valve pointed at one bottle, then kept an eye on the indicator. When it turns red, that one is empty and it has auto switched to the alternate. So then you switch the indicator to the alternate indicator turns green, then go fill the. primary, put it in open it, then the alternate is now the primary until it empties and switches to the first.
