the tanks are supposed to be filled by WEIGHT! the reason for that is so there is room for the propane to expand inside the tank as the temp goes up. there is both liquid and vapors inside the tank you have onboard. ...

You need to learn about what OPD stands for. No weighing necessary.

This is wrong- the OPD is meant as a backup safety- overfill protection device- just protecting from bone headed attendants- cylinders should always be filled by weight, and the OPD should never be used as a gauge to fill.

Here on the left coast the vast majority of the attendants use the OPD valve as a fill gauge. [url=]:E

I have NEVER had any of my tanks weighed while filled. None of the stations I go to have scales. NONE of them.

I just got back from a 10 state vacation and none of them weighed while filling either.

In my state they connect the tank and open the vent, kick on the pump and pump until the OPD kills the flow or the tank starts to vent. (that is their two safety system safety) They turn the valve off, tighten the vent, vent off the hose pressure, disconnect the tank and done.

If this is improper or illegal there would be a lot of people getting in trouble because this is the way it is done every time I have had my tanks filled.
