Dometic propane tank sensor

Has anyone purchased one of these? I saw one demo'ed at the RV dealer yesterday. They had a $65 price tag on it but good old Amazon has them for $50.

Search "gascheck" on Anazon. Looks like the same thing. A search Google for " Truma levelcheck" will yield a similar product. These devices look like a real solution to propane level sensors.

For $20.00 at Costco I got a gauge that screwed into the valve the hose then screwed into it and it tells me at a glance how much Propane I have left...

From what I've heard, a measure of tank pressure is not a good indicator of remaining propane.
Our local propane dealer tells me that they only true measure is by weight. That would be great if the tanks each sat on a scale in my 5er.

$12 at Walmart...I had an issue with these where it would work for a day or two then shut itself off. Would not allow propane to flow. I tried a second one and it did the same thing.

I saw the Gascheck on Amazon. Price was reduced by about half but far from good reviews, more 1star than any other rating. The Truma looks interesting though. Seems it was awarded best new product or technology in Germany.
We ran out of propane last weekend, thus this search for a prevention method. Unhooking and shaking those big tanks is not the answer.
*****Update*****
The Dometic device is made by Truma, according to their website. Looks like a repackaging only deal.
May have to get one from Amazon and do some testing before their return period runs out.

We carry a bathroom scale, I use it to weigh the tank when there is a question.

My old trailer had only one 20# propane tank, and I was always afraid of running out of LPG. I purchased one of those screw-in gauges and was not happy with it at all. Would indicate a full tank or an empty one, but nothing in between. I ended up putting it on the grill, but even there it wasn't much good. I mean I could already tell the tank was empty because the furnace/grill wouldn't work!

The "Truma/Gascheck" looks to be a much better solution. JMHO!

Apparently DOMETIC is not yet offering the Truma product in the US, but it is available on the Truma LevelCheck or the TRUMA sites. Amazon offers a MosCap product. It is probably only a matter of time before it is sold through Amazon ...

Mine have worked perfect since I got them 2 years ago.. guess this proves you get what you pay for.. Walmart sells cheap schlock and I avoid shopping there..

I used to use the screw in gas gauge, but it never worked.

I now have the Truma. It works very well. I can tell exactly where the propane level is in my tanks.

It is not the cheapest tool, but in this case it is well worth the money IMHO.

Cosmic is correct. When you get a tank filled, they go by weight, not volume (which is different at different temperatures). As far as I know, there is no way to determine the volume of a gas cylinder or tank by using a pressure gauge. The pressure is the same whether full or nearly empty. Just think about this - does your refrigerator, stove, water heater, etc operate any differently as the tank gets lower, by volume? No. Because the pressure is the same all the time until the tank is empty.

I've seen no gauges that would convince me otherwise.

I'm with Cosmik and Scout, the screw in gauge will tell you there is "some" or "none" in the tank. It measures the pressure in the tank not the amount of liquid. The pressure will be constant until there is no (or very little) liquid in the tank. Do a Google search on "vapor pressure" for the details.

My local propane shop sells a mechanical gauge, has a float extending from the valve into the tank. A magnetic gauge clips to the tank valve and reads the position of the float from a linkage in the valve.

I use the hot water method. Pour hot water over the side of the tank. The hot water will heat up the tank wall ABOVE the LPG a level in the tank. Run your hand done the side of the tank. It will be noticeably warmer above the LPG level in tank and noticeably colder when you reach the level of the LPG. Keep in mind a full tank is only going to be 80% of the total tank volume.

Works pretty well for me and is essentially free.

Here it is on Amazon.
http://www.amazon.com/Dometic-LPGC10...productDetails
On the Truma site they show their gas check as available at my local rv dealership and when I first saw one there it was the Dometic. From these two pieces of info I'm assuming then that the dometic is made by truma and sold under both names.
The little internal watch batteries are replaceable and truma claims 2000 uses per set.
I wonder if these could also be used on holding tanks.....

Interesting thought. I doubt it though. The following is stated on their website:

"For all steel and aluminium LP gas tanks with a diameter of 7.9 to 13.8 in"

Fill level indicator Truma LevelCheck

I suppose the new "see through" propane tanks would not work with the Truma device. Of course you would just be able to see the propane level on those types of tanks.
