This question could be asking when a person knows the tank (1) requires a refill because it is low on fuel or (2) How a person knows if the tank satifies current safety criteria allowing it to be refilled. For the first scenario related to low fuel: Most Operators at filling stations advise refilling only when the tank is empty. The normal method to determine an empty tank is simply when there is no longer enough pressure in the tank to create a flame. Another method could be to use total weight. An empty tank for most home barbecues is about 20lbs vs a full tank that is closer to 40lbs filled. You could also ask your local operator, some of them are quite practiced at determining weight by feel and some can feel whether there is any liquid fuel still in the tank. For the second situation related safety criteria. Propane tanks are subject to Federal Safety Regulations to ensure tanks which might present a risk are not refilled. At a minimum, All tanks have certification dates stamped into the metal and cannot be over 12 years old (and recertified every 5 yrs) and they must also have a current type filler valve called an OPD. If you are not familiar with these and other requirements it is safer and faster to visit your local fuel station operator for assistance.
It doesn't make a difference whether your using propane or green gas I'm not sure why they call green gas green gas because all it is propane with silicon oil in it but if you buy a propane adapter with an oil port you basically made green gas.
In examining the costs of natural gas vs. propane, the rates of local energy utilities and propane companies vary and will need to be taken into account for correct comparison. But to get the cost comparison between the two fuels, you must compare the cost of the energy value which can be obtained through local propane companies and utility companies. While utility companies provide price per cubic foot, propane companies provide price per gallon. Natural gas availability will usually determine whether or not propane can be used because many municipalities will require the use of natural gas if a business or residence is within a certain distance of a natural gas main line.
