I understand exactly what your saying, but the condition I was having The dew point reading would give me a subcooled suction line, and the bubble point reading was only one that made sense because as we know now I was coming back straight liquid.
Follow what is actually happening with the dew point/bubble point.
The area between the two is the saturation area of the refrigerant and liquid can exist at any point between the two.
Glad you got it solved! The first one we saw took us several trips over a couple of days to figure out also! I guarantee you'll never forget about it and if you ever see it again you'll go right to the problem!
