Explain this. It is the standard Float Level unit for ASME tanks. It is what I have seen and repaired for 40 years. While it does use Magnets, it IS Mechanical. Doug
What I'm saying is there is no "direct mechanical linkage" between the float and the gauge needle itself. They are both attached to magnets separated by a layer of brass. Just as if you were to place magnet under a piece of glass and lay another on top, moving the bottom one will cause the top one to move. The movement will not be completely smooth all the time. It moves in spurts only when the pull of the lower magnet overcomes the drag is overcome of the one on top of the glass. It's not as if the float was directly directly turning the same shaft the gauge needle is connected to - they are separated by a layer of brass machined under the gauge dial in threaded plug housing which makes the gauge leak proof.
When the tank is being filled and the purge valve is open - that's not "air" that's being purged, it's propane in its gaseous form. All the appliances use propane in this form. The liquid propane is boiled off before it leaves the tank.
You can use this pressure - temperature chart to see the pressure in the tank at various pressures in the tank and viceversa: HC-290 (PROPANE) PRESSURE - TEMPERATURE CHART
