I got one of those alarms as a gift a couple years back Dale, but never could figure out the voodoo that made it work, so thanks for the explanation.

The propane in the tank remains liquid because of the pressure. As the valve opens and gas bleeds off the pressure at the top of the tank reduces allowing some of the liquid to vapourize and become gas. Only as much as the pressure will permit. This is how those colour strip tank gauges work. The point at which the propane changes from a liquid to a gas there is conversion of latent heat, the amount of energy required to change state from liquid to gas and this temperature change is reflected in the colour of the strip. A daughter sent me an electronic out-of-propane alert device a year ago Christmas. It sticks to the side of the barbecue tank by two magnets oriented in vertical alignment on the rear of the device. I presume, because these are surrounded by a sort of rubber foam that thy include thermesters or some similar temperature sensitive devices and the circuitry sounds an alarm when they detect a difference in temperature between them, the upper warmer than the lower. You locate the alarm near the bottom of the tank and when the propane is down to that level it begins to twitter. It seems to work.

In the hot sun the tanks do get warm. I persume that why the instructions are to turn thetank off when not in use. ----- Original Message ----- From: "Joe Plummer" <joeplum...@tds. <mailto:joeplummer%40tds.net> net> To: <blindhandyman@ <mailto:blindhandyman%40yahoogroups.com> yahoogroups.com> Sent: Friday, January 15, 2010 8:16 AM Subject: [BlindHandyMan] Re: Propane gas.

Bob, Very good point about the propane. I've read that as well, but forget about it, since I've never known anyone to heat with propane. I think that is because I've typically lived in cold climates. I think propane heat is more common in places where heat is not a necessity. I could be wrong there though. -- Blue skies. Dan Rossi Carnegie Mellon University.
