Propane - when is a fill a true fill
Over the years (12) I have had my propane tanks filled using two methods to determine when the tank is full, by weight using a scale and the second filling until propane escapes from a bleeder valve. ...

I have for years been getting my propane tanks filled at Flying J or Love's and they charge by the gallon rather than flat rate. The issue of getting a totally full tank is less important when paying by the gallon.
Flying J typically just fills until gas starts bleeding out. Twice this has caused my tanks to later start venting gas due to being overfull. The one time the tank was filled at around zero degrees and started venting when it was 70 degrees in Florida. Another time the tank started venting sitting in the sun. Neither one of these tanks would have had an issue if filled properly by weight.
If a propane cylinder is properly filled, whether by weight or volume, it is filled until the 80% valve shows liquid propane OR the OPD shuts off the flow, whichever comes first. IF the flow is stopped at that point, the cylinder is NOT overfull! In fact, if the cylinder has a properly functioning OPD, it can not be overfilled!
If it does not have an OPD, it should not be filled!
