Propane tank gauge

PXL, That was a visual I really didn't need!

Probably have flamingos on 'em, huh?[pink]

Run Forest, RUN!

The tank empty (tare) weight is stamped into the side near the top or on the handle/valve guard.  Generally about 20 pounds or 8kg for the common 20# capacity tanks.  Example "-TW8.2KG-"   This is used by some filling stations to determine when the tank is full.
Remember, it will need to be completely free of it's mounting bracket to get a meaningful measurement.

I looked up those steak savers and found that there are inexpensive valves you can use to refill the little 1 pound bottles from a bigger tank.  Safe?

The "new" tanks are required to have an OPD equipped valve.  These have a float that prevents the tank from delivering liquid propane when inverted as the older tanks would.  Descriptions of refilling the one pound cylinders from bulk tanks are from before the OPD requirement (over 10 years).   The most that will happen now is a little vapor will be pushed into an empty cylinder which, for any practical purposes, is still empty.
The "steak savers" adapter along with one or two disposable cylinders is a good back-up plan.  I know at least two T@B owners that use only these small cylinders. They save weight and space and are easy to find.  One will provide many hours of cooking and heat.
Have fun!

TerryV6, I have filled quite a few. There are several threads on youtube to fill these cylinders. My suggestion is to watch several, and pick the method you feel most comfortable with.
rfuss928, I don't "invert" the tank when filling the smaller ones. I have a 2x4 I set the bottom end on with the tank sideways. I also use a small set of hemostats to use for the pressure release valve on the small tank while it is filling. I have seen videos of people who turn the tank totally upside down. Didn't look too safe to me, so I chose the sideways method.

Thanks rfuss928, I am, believe me. I really don't want to end up in the neighbors yard!
