Yes and no. Most gauges which are built into common "barbecue" (20-lb) tanks are indeed simply those nearly useless pressure gauges. The exception is Manchester's SureFlame, which is an actual level gauge. The dial is a clip-on accessory, which is magnetically coupled to the float inside which triggers the OPD valve. It provides an actual (if not terribly precise or accurate) level indication.
Secondly, some cylinders have gauges which show the amount of
LPG contained within the cylinder. The in-line gauges are less desirable
than the in-tank gauges that have floats that sense exact liquid level.
(This in-line gauge is one that is the FULL / EMPTY gauge for 25 bucks.)
See The Tank and SureFlame advertisements for in-tank float gauges.

Just to reset this thread... the question was from fastEd: wrote:Ebay has an in-line analog propane tank level gauge. You've probably seen them, about 25 or 30 bucks. How do they work?

The gauge on them will flutter as the tank moves from horizontal to vertical, so they must have floats in them....
