In fact, it holds 20 lbs when filled to 80 per cent capacity.

Given that the government sends inspectors around to ensure the gas pumps are accurate, how long do you think Husky could get away with charging for 20 lbs. and delivering less?
I am not assuming I am asking and not incriminating Husky, In My first post I ask if that capacity was taken in to consideration by the manufacturer hence the response of the 80% fill rule table given by vermilye, accordingly to You that expansion is taken in to consideration by the manufacturer accordingly with the 80% rule it is not, since there is a margin of safety.

Out here in California the tanks are filled by volume, not weight. I've never seen a scale at a propane station.

Thank You santacruzer: and Your tanks are filled up at what percentage of the volume?

Filled to 80% of volume capacity, as far as I know. I believe the mechanisms inside the tank start overflowing at that point, and it's when the operator turns it off. It may be semantics, but I consider the tank full, since it can't be filled any further.

Yes, that is correct: it contains 20 pounds of propane when 80% of the tank contains liquid and the remaining 20% contains vapour.

We still pay for 20 pounds when We actually get only 16.
The 80%=20 pounds level is based on a standard temperature. If you fill by volume in the tank you would get less when it is hot. If filling by weight, this doesn't matter (you still get 20 pounds, and the level is a bit higher); if filling until the 80% level is reached, then you'll get less. If you are charged by actual amount (rather than a fixed price for a tank), then the meter should be temperature-compensated so you still pay for only what you get.

No - the fill to 80% of the tank volume is 20 pounds...

Again, correct.

This varies by region. Anywhere I've filled a portable propane cylinder, the fill amount is checked by weight.

It's a per gallon charge...just like gasoline. I pay for what they put into the bottle, even if the bottle is only capable of being filled to 80% of capacity. I don't recall the cost per gallon, it varies from station to station.

  1. When filling by weight, the operator should shut it of when 20 pounds of propane is reached.
  2. When filling without monitoring weight, the liquid level port should be opened: this is a small valve connected to a tube with its open end in the cylinder at the 80% level. When the port starts spitting liquid, the fill is stopped.
In either case, modern small propane cylinders have an Overfill Prevention Device (or OPD), which is a valve that is closed by a float when the 80% level is reached. This is a safety backup, not the primary method of monitoring fill level.

By either method, when the liquid level reaches 80% of the tank volume, the tank is full.

Thank You Brian: this answer clarifies My question. a temperature compensated meter should be standard in every dispenser.

No, we are paying for what we get, regardless of the size of the container. A common propane tank is called a 20-pound tank because it holds 20 pounds of propane when filled to the proper level. We get 20 pounds, and we pay for 20 pounds. I think that's 4.6 US gallons, so santacruzer gets a receipt showing that his 20 pounds is 4.6 gallons, although the tank is bigger than that (about 5.8 US gallons), because that's what they correctly put in.

I agree, if a volume meter is used. In Canada, both gasoline and propane meters are temperature-compensated. I know that is some states gasoline meters are not temperature-compensated, but I would expect propane to expand more with temperature than gasoline. It will say on the meter, often expressed as a label that says something like "gallons at 65 degrees F" (or whatever the standard temperature might be down there - it's 15 C here).
