The correct measurement is when liquid propane begins to escape through the bleeder valve (or maybe you have an auto-stop valve?) during filling.  Not sure of the exact gallons this point is, but its either 2.4 (80% of 3 gallon) or 2.7 (90% of 3 gallon).  The tank size is 3 gallon, but of course you dont fill it completely.  Assuming you are filling an empty tank; 2 gallons is a safe fill stopping point so you dont have any liquid propane accidents.  My last fill, the attendant wasnt watching and ran it up to 3 gallons and liquid propane began spewing out the bleeder, he couldnt get the fill hose disconnected nor get to the bleeder very easily, with the large gloves on.  Liquid -44 degree propane continued to spew out all over the tank, the skid plate, and the fill hose, for about 10 seconds.   I much would have rather he just stopped it at 2 gallons and avoided the mess and situation.
