Ok, this sounds strange, but I tell by wt. I have a 7.5 lb tank and can tell when lifting it if it is getting low. I also know that if I torch x2 per week, the tank lasts one month.
I would be interested in this for other though. Will be looking to see what type of response you get.

December 29, 2003 at 10:20 pm #1021015I have a 70 pound tank and I’m not lifting THAT thing anytime soon! Plus it is bolted to the house for security. Please don’t tell me that’s a bad thing!
Anyway my current way of checking is knocking on the tank!:D
But I really have NO idea WHAT I am listening for! :confused:I have had it for over three months now and torch at least 12 hours a week, on my Hot Head.
Thanks for responding Lara!

December 29, 2003 at 10:29 pm #1021011when my 70 lb tank was running out every time It had a foul odor right before it emptied out, maybe a 15 minute warning period before it died
Don’t have the tank anmore we upgraded! Yeah!!!!!!!!!!

December 29, 2003 at 11:33 pm #1021012If you are using an air-fuel torch like the Hot Head or Quiet Torch, you DON’T NEED A REGULATOR. These torches are designed to run on tank pressure. If you are using a torch that requires tanked oxygen or an oxygen concentrator, then you’ll need regulators for both the oxygen tank and the fuel tank.
The way I used to tell when I was about to run out was by usage. I knew approximately how many hours I would get out of my tank. Another way is to weigh the tank when it’s full, note the weight, then weigh again later and you’ll know how many pounds of gas you have used up.

Thanks Alex.
I do know I don’t need a regulator. I was hoping there was a more precise way to gauge how full my tank is.;) I do not see me “weighing” a 70 pound tank easily.
Oh well I guess I’ll just call the welding shop and see what they say.Thanks for the help:)

December 30, 2003 at 10:21 am #1021014You can’t tell how much fuel you have left by using a pressure gauge if you are using liquified petroleum gas as a fuel.
You can weigh your tank (with regulator, etc. installed) when it is empty. Then you can weigh it at any time to determine how much fuel remains.
Or you can buy a strip that sticks on the side of your tank that will show the liquid level inside the tank. I believe it works based on temperature differential.

December 30, 2003 at 10:23 am #1021013Ah, Kim, sorry, I misunderstood.
The regulator will not help you determine how full your tank is because of the nature of MAPP gas. It is a liquid inside the tank and it volatalizes into a gas to maintain pressure at around 100 psi. The pressure guage will read 100 psi almost to the end.
You can use a pressure guage to determine how much oxygen you have in a tank because it’s a gas inside the tank and the pressure falls in the tank as you use it up.

Take pan of warm/hot water (Not boiling) and dribble water down one side of tank. When pan is empty, run hand down side of tank. You will find a line where tank changes from warm to cool. This is the level of the liquid (MAPP or Propane) in tank.If you don’t find the “line” your tank is probably totally full or pretty close to empty.

Anyway…that sounds like the easiest way so far…..I really can’t see myself picking this thing up to weigh it on my bathroom scale LOLThanks so much for the help. I have had it for about three months and I just know it will run out at the most inopportune moment if I don’t check it!!
Thanks again!!
KimDecember 30, 2003 at 2:39 pm #1021018My Ex-husband just bought me a 30 # tank for X-mas, from my kids. When he hooked it up, he brought along the hose and a 2 guage thingy ( technical term ). 1 guage reads the pressure, the other guage shows how much fuel is left in the tank. Sorry thats all I know, I’m pretty sure he knows what hes talking about seeing he welds on a daily basis. And you will never again hear me admit to him knowing what he is talking about

In WisconsinDecember 30, 2003 at 5:12 pm #1021010I use a 7.5 tank of MAPP and work everyday for about 1 to 2 hrs. and get a replacement about every month to 5 weeks. I can tell when I’m getting empty just by the flame – it gets weak.
