I always just leave one tank closed. If It runs out I open the other and fill the first.

Having two tanks helps, yes. Not everyone has two though.
I use Jons method, and the palm of my hand. You can feel the temperature change by palming the side of the tank and running it down until you feel the temp change to MUCH colder.
It doesn't need to be overly accurate, but it does give you an idea on where your liquid level is.
I have the pour the hot water thingy stuck on mine too, but I generally have only used it when the outside temp is so low that it's hard to feel the difference on the tank. The smell method is a giveaway that I have maybe 2 days of normal use left.

Propane tank level gauge
...To me, I rarely use propane tank at all, so it wouldn't bother me that much for this issue. That's why I installed the gauge which was bought from Cosco. I believe ab 10 bucks. To go in depth, it sounds like no gauge in the present market in which indicates how much propane is in the tank, accurately. IMO, if I want that due to frequently use, I would make myself an indicator. Here is what I would do: when the tank is empty, drill a hole in the tank, thread it to install a pressure gauge. After that, fill the tank to full, the gauge will indicate at certain scale, mark it with permanent marker. From now on, I would know exactly what level of propane in the tank at any given time...Just my thought....

Camping Mama said "tanks" (plural) in her original post. I have two tanks, and the double tank regulator shows me when the primary supply is empty, and it switches to the backup seamlessly. Then I move the lever to the other side and replace the empty one. The fresh one becomes the backup. It seem to be working well. Since it is possible to go quite a while on one tank, there is plenty of opportunity to check the indicator. I am quite happy with this system.

Lp tanks are pressure vessels and you don't want to start drilling your own holes in them. If you do so I doubt if anyone will fill them.
and
Lp gas maintains an almost constant gas pressure, regardless of volume remaining, this is why they tend to drop suddenly just before being empty.

For 2 tanks or double tank, this is what I would do: Using tee fitting, parallel hook up both tanks without any valve before tee fitting, install indicator after T fitting. The valve will be installed after T fitting. When in use, first open the valve then open one tank until this tank is empty. Next open the second tank until it is empty. That way, you would know both tanks are empty. Fill them up both at the same time. This way you could avoid complication of double tank hook up and still know when will be the time to fill them up. Just my thought, theory though...

...This is what I learn thru: discussion. BTW, that's just my thought, in theory, not practical. But if an indicator of propane tank is made, one could apply similar principle to utilze it, not necessary as pressure like I thought....Just an input...

Gotta find your humour where you can.
Interesting that people bought these three items.

Thats intreating as well. My furnace doesnt seem to have any issues with it on. What furnace are you running? wondering if the regulator on your tanks is perhaps set a bit lower than the on mine.

The pressure in the tank varies with temperature making any type of pressure gauge useless (ideal gas law?). I've used the "hot water down the side and feel the temperature" trick as a rough guide. When I think it's getting low, I look for a Tractor supply with a propane station. They meter the propane and their prices are reasonable. Raz

2] Remove the tank before a trip and weigh it on a bathroom scale.
18 pounds is empty,38 pounds is full. Estimate the need for the trip and switch tanks if necessary before leaving.
Using the weighing method requires the purchase of a second tank to get full use of the propane. We have a grill at home on which we use only "near empty" tanks. This second tank can be filled before a trip if there is not adequate supply in the trailer tank.

I vote this as the best answer. The bathroom scale works great. If it's too much trouble to take out the tank for weighing, get a tank with internal float gauge. I bought such a tank last October at Sam's Club (less than $40 IIRC) and I expect I'll enjoy using it this summer.

Keep in mind that the "Exchange Tank" system is about the most expensive way to buy LP gas. I have seen it as much as 3X propane dealer price.
I'll stick with the Stick-on strip and hot water, about $3, works every time.

I keep a few one pound green propane bottles to run the weber grill and have an adapter that let's them be connected to the furnace propane line.
When the 20# runs out I can run the furnace approx one night on a one pound bottle. And I know it's time to refill the 20#.

Do you have any info on the adaptor for the 1 lb tank to the furnace line?

I have one as well, - it allows me to switch from using a large 20lb tank to the small green disposable tanks for the portable stove or BQ if need be. Sorry no picture of it but i picked it up at a local hardware store. Should be pretty easy to find one at any shop that sells BQ's.

My bad. I was assuming we were talking about two tanks.
