LP Gauge that work???

[buckeyegal]

Anyone have a reliable and accurate means to tell LP level without taking the tank out of the trailer? Have tried the magnetic color coded ones (worthless).

also tried a pressure gauge on my grill few years ago and all it did was decrease pressure grill & interfere with lighting; do NOT want that on my 5th wheel.

thanks.

There is an actual float gauge and valve that can be retrofitted to your existing 20 or 30# bottles, or you can buy new tanks with gauges in them.

There are fiberglass or composite tanks for propane that you can see how much is in the bottle.

Don't know if they are in 30#. I saw one in a 20#. As u moved the bottle you could see the gas move in the cyclinder. Sure they are not cheap.

I purchased an LP gauge at walmart in the BBq section. Its a pressure gauge that you screw into the bottle and then attach the gas line. Its not perfect, but its close. At least you will have some ideas how low your getting.

I think the best method is to run one tank at a time. When you run out, manually switch to the other tank and replace your empty. Yep... You might run out in the middle of a shower or night... But a simple change-over is way faster than a trip to town.

Pouring hot water down the side of the tank and feeling where the water turns from hot to cold always works for me.

I use a luggage scale - weight doesn't lie - You can buy one on Amazon for about $15 (Walmart also has them).

I recently saw a new way to check the propane tanks. You might be interested in it. I am thinking about one for myself. It is a "Fill level indicator Truma LevelCheck"

Here is the link: levelcheck.com

I wouldn't mind hearing feedback from anyone that has one.

I use the infrared temp gun we travel with and can tell levels of the tanks with it. There is a good temperature change on the bottle where it has propane and where it doesn't.

I bought one of these on Amazon. I seems to work fairly well at determining the liquid level in the tank.

Windjammin, I checked Amazon.com and after reading the reviews I don't think I would buy that gauge.

X2 Plus you can use it to check your wheel bearing temperatures when on the road.

Cheers!

+1, this is my preferred method. That, or weighing the tanks (a pain), or a built-in gauge are the only reliable methods.

The add-on pressure gauges are useless due to how the propane is extracted from the tank. Propane gas is boiled off of the surface of the liquid propane, and that surface area is constant the whole time until you hit the lower "shoulder" (rounded part) at the bottom. At that point the pressure gauge will drop, but that is a very small time frame and you would be lucky to notice it.
