I learned something today, my local refiller stopped using the scale and the meter stopped at the appropriate number. Now I know why. I always take in empty tanks.

I'm learning too. I always thought it was a back pressure shut off when the OPD valve closed, I did not realize about the scale shut off. I'm going to try another refiller with a fresh rhino tank and see what happens.
