Cylinders are labeled by how much propane they hold. 10lb tank holds 10 lbs of propane, 20 lb tank holds 20 lbs of propane, 30 lb tank holds 30 lbs of propane. 20 lb tanks are more commonly known as BBQ size tanks. These cylinders are meant to hold 20 lbs of propane @ 80% of the tanks capacity. Blue Rhino is most certainly 'short-filling' their tanks to line their already bulging pockets. Also, Blue Rhino puts a plastic 'sleeve' around its tanks which advocates rapid rusting resulting in an ugly and sometimes unsafe cylinder. I have worked at a refill station for 10 years now and I can't tell you how many complaints we get about Blue Rhino tanks. It is not unsafe to put 20lbs of propane in a tank, UNLESS that tank is exposed to 120 degrees F or above, at which point, the pressure relief valve with discharge to reduce pressure inside the tank. You only want 80% of your cylinder filled because propane expands and increases in pressure when exposed to temperatures between 66-119 degrees F. This is why you never want to store a full tank inside. If in the case the pressure relief valve does blow off, and the tank is outside in a highly ventilated area, the propane will dissipate. Also, propane is heavier than air, so if you do have a leak, the propane will settle in low laying areas. Shut all electricity off and call your fire department if you suspect a leak. As for this new 'magnetic valve', I have only seen a few up in MA over the past 10 years. I empty the cylinder, and replace it with a fully functional OPD valve (DO NOT TRY THIS IF YOU ARE NOT CERTIFIED), this way it can be refilled wherever the rightful owner of the tank wants it to be refilled. I can't knock Blue Rhino for its convenience. It's about the only propane you can get at midnight at a 24 hr Stop & Shop. Try finding a refill station open at midnight (never!) If you think Blue Rhino is ripping customers off only filling to 17 lbs of propane. AmeriGas only puts 15 lbs in their exchange tanks!! With all this said, stay away from Blue Rhino and Amerigas. Blue Rhino is now owned by FerralGas which is the largest propane supplier in America. Support your local mom and pop refill stations. If your using Blue Rhino, your just lining the already rich pockets of corporate America. God Bless the USA!

I found the gauge at Harriet Carter. Ended up buying 6 of them. 2 for us and 4 for friends, they really do work and I never run short of propane. Last week friends of ours ran out while cooking for a houseful up north. He went over to the neighbors cottage and "borrowed" their propane tank. Later that day the neighbor mentioned that someone had "stolen" the propane tank, but not the grill! Our friend quietly returned the tank when the neighbor wasn't looking. Shame on him. Well, he's getting one of these gauges! Kathy G in MI

A local Richmond, Va TV station recently did an expose on this industry. As it seems in the South Propane Dealers are NOT REGULATED in terms of home much they charge, what delivery fees are or what proper business practices & policies should be. This is why they get away with locking you in. Charging you more if you are not "their" customer and putting you on a minimum purchase required plan. It is all done in the name of their profits not yours. Personally after I found out I could buy my own 500 gal tank for 1500 & get my excavator to bury it. Pay a plumber who was a gasfitter to run the line to my house & fireplace & generator . I decided it was cheaper to do it myself & contract the jobs. Their charge would have been 5500. Then I would also be locked in to purchase my fuel only from them. Thats a bunch of crapola. Saved 3 Grand doing it my way. My excavator charged me only $200 to bury it & the plumber charged 800 for the line & the fittings. Their is very little required maintenace for this tanks. Don't let them pull that ruse on you!!!!.

You cannot tell how much propane is in the tank by simple pressure. Find a liquid crystal strip for the side of the tank. It measures the lower temperature of the liquid compared to the gas above it. As long as ANY liquid remains in the tank the pressure gauge will read the same. it will move with the temperature, but does not indicate how much liquid is left. By the time the pressure starts to drop the liquid is gone and you have only a tank if gas remaining (though at a high pressure initially).
