How do they work?
How do gas level indicators actually work (and I don't mean you put the magnetic strip on the side of the bottle!)?
How do those gadgets you fix on the OUTSIDE of your water tank to tell whether there is water INSIDE work?

They are temperature sensitive. The gas(and water) is stored as a liquid and is colder than the gas that is gaseous (or the air in the water tank.) Since the part of the tank that is filled with liquid is colder, the magnetic strip turns a different colour where it sits against the colder part of the tank. Hope that explains it.
but if that was the case surely the magnetic strip would need to be the entire length of the bottle?
I'm not sure what the one you have looks like, mine have run vertically from 20% to 80% of the height of the tank. Could post a picture?
