There will be a moveable pointer or other device on the regulator if it is an automatic change over one. Most two tank systems have the automatic change feature. You will see a window with a red or green indicator as well as a pointer or other movable lever if you have one.

BBQ tanks that you buy pre filled are convenient, but pretty expensive in terms of dollars per gal of propane. Not only that, but they generally (or very often) are short filled to only 4 gal rather than the 5 they actually hold, making the gas even more costly.

But I understand the convenience, especially if you don't use much propane. Only you can decide if the convenience trumps the cost.

Look at the collar and you will find the Tare Weight (TW). This is the empty tank weight. Somewhere around 18# for a steel tank. A 20# propane tank when full will weigh 20# above the Tare Weight.

I use a luggage scale with a memory pointer feature. The memory pointer records the maximum weight encountered so I don't have to struggle with lifting and reading the scale at the same time.

The tare weight for my stock 30# cylinders is 26 lbs, so I prepared the following table which I laminated and is attached to each of my tanks:

Full - 56 lb
3/4 - 48 lb
2/3 - 46 lb
1/2 - 41 lb
1/3 - 36 lb
1/4 - 33 lb
Empty - 26 lb

Obviously, there is more work to this solution, as one has to remove the tank covers and the hoses to get a true weight.

I do this before my trip starts to get a baseline for where I am and periodically re-weigh during longer trips to determine a pattern and anticipate when there is a need to switch over and/or refill.

I realize that not everyone is willing or able to lift almost 60 lbs to utilize this method. My Weber grill at home has a simple usage indicator built into it where one hangs the tank from a built in scale with indicators at 0, 1/4, 1/2, 3/4 and full. Would love to incorporate something like that but would have to secure the tanks somehow for travel, something my Weber grill does not have to contend with.
