Inaccurate Propane Tank Gauge - 2003 F350 21’ Majestic

Has anyone with this RV or similar had problems with their propane tank gauge? Mine reads 3/4 when the tank is full. What was your fix?

Often, the tank IS full at 3/4.
Expansion dictates.
You'll have to move the external sensor, if yours works like that, to get a full reading when you really have 3/4 of a tank.

The legal amount allowed to fill any propane tank is 80% to allow for expansion.

Just for information - there is actually a float gauge inside the tank with a moving magnet. The gauge on the side or end of the tank also has a magnet of opposite pole (they are attracted to each other). The gauge on the outside of the tank also contains a variable resister than powers the gauges inside the coach. Your coach is setup to work on gaseous propane, but the tank is filled with pressurized liquid propane known as LPG. There needs to be a phase change surface in the tank to convert the liquid propane to a gas. Thus a need for a max fill of only 80% of the capacity of the vessel.

If you want an accurate reading of your propane tank get a MOPIKA TANK CHECK. It is a Bluetooth level reader. Check it out on Amazon and you tube.
