Do you mean a pressure transducer? If so, that's not going to tell you contents just vapour pressure the same as a pressure gauge. Weight dependent resistors (load cells) might feasibly give an indication of bottle weight hence contents.

As I suggested. I even suggested a way to compensate for the differences in the empty weight of the LPG tanks but was shot down.
Just weighting for a display to test it out using this project as a starting point. https://circuitdigest.com/microcontroller-projects/arduino-weight-measurement-using-load-cell
