Anyone use hopper railcars and have a better way to check if any material is left inside rather than banging on the side to see if it sounds hollow or climbing on top with fall protection and opening the lid and looking inside?

In my head there should be some sort of ultrasound machine that can give some sort of reading on what's left in a bay. Hopefully not too expensive of course 😂 but at this point I probably have decent justification for how much material we are sending back and probably getting double charged on.
