I think I usually hope to see 41 lbs hit the scale after I tare it out prior to the transfer. Hasn’t been happening lately, but not like I can do much about it when it doesn’t.
Last transfer a couple weeks ago was 38.7, and I just stared at it for a little bit wondering why?? Why can’t I get a full keg? I opened up the torpedo, saw the floating dip tub in all the trub and got over it.
I have no method to measure how close a keg is to getting empty either other than opening up the kegerator and lifting it up and guessing. Which is a PITA when navigating all the various other lines and kegs I don’t care about at that moment.
