Closed loop transfer....conical to keg build question

[Nagorg]

I did my first closed transfer. Overall it went pretty slow but I think thats partly due to the TC fitting I got from Amazon; its got a tiny hole... Tinier than I think it should be.
I needed it in a hurry because of piss poor planning on my part. Brew Hardware was out of stock on the one with a 1/4 Male Flare fitting. Brewers Hardware has one but anyway, I got the one seen below. I think I'll order one of the MFL ones for the next time.

I also learned that either my corny kegs dont hold 5 gallons, my scale is off or my beer weighs less than 8.34 lbs per gallon. Both kegs started flowing out of the gas line before 41.7 lbs. One was around 40 lbs and the other was just before 39 lbs. Guess I'll stop at about 38-38.5 next time for ~4.5G...

Question... How do you keep from overfilling your keg in a closed transfer? I love the idea of this but am not sure how I'd know when to stop before getting it too full.

lol you don't.... i have done this a few times. keep track of your volumes how much you rack off how much you have going into the fermenter etc. i try to have 5.5G to the fermenter and run off .3G for yeast and trub.

Uh... Yeah, I keep track of my volumes. Thats not the question. Prior to a closed transfer I could see the level of beer as its filling up the keg. I could see the "5G line" and also where the short gas tube was so I could stop filling at the right time. Remember, I cant see the conical level dropping since SS isn't very transparent.

Anyway, I think I figured out why my kegs only hold ~4.5G. The two pin-locks I was using last night are my two shorter ones. It never occurred to me that they held less beer due to their shorter height but .... DUH! I like the shorter ones because I can set them on the hump in my keezer and still have room to close the lid without binding the hoses.

So, I'll keep that in mind on the next closed transfer. And I'll hopefully have a TC fitting with a more properly sized hole by then to speed things up a little.

Do you fill with counter pressure? Before putting a spunding valve on the gas peg, I would see foaming in the receiving keg.

Also, presume you tare your scale before filling, but filled hose weight, etc. can give some inaccuracy (unless tare with all in place) that could be on the order of a pound or two.

No spunding valve. I'm not transferring carbonated beer in my case. Yes, I did tare my sale when hoses were attached and before starting transfer.
