Subject: [C320-list] How to assess Propane fill

Here is an accurate way to measure the level of propane in the tank. The
only thing you need is a scale to weigh the tank.

All propane tanks will have two weights stamped on the collar (top handle.)

	TW (Tare Weight) - weight empty
	WC (Water Capacity) - weight of tank when filled with water.

Regulations limit the propane level to not exceed 42% of the WC

Liquid propane weight is 4.2 lbs/(US)gal.

My "10 lb" aluminum tank reads: WC=23.8 and TW 10.0

Allowed propane weight it 23.8 x 0.42 = 10 lbs

Propane weight + TW = weight of tank when full (10 + 10 = 20 lbs)

Or, 10lbs / 4.2lbs/gal = 2.38(US)Gal of propane in full tank

I.e. if tank weighs 17 lbs, 17 - 10 TW = 7 lbs of propane at 4.2 lbs/gal =
1.67 gal of propane or 70% full

Some stations sell by gallon, others by weight. So, figure both and compare
to what the attendant says when full.

I remember a while back some were trying to figure out how much propane they
had in their tank. I pulled mine this weekend and had it filled. I did not
weight it before Dillon but I did when it was totally full. The tank and
propane wet 20#. Tare weight on the tank says 10.00. 

Good for thought.
