How to tell if dewar isnt filled all the way
 

Is there a way without wasting ln2?
Keeping track of use minus your dairly loss I guess is the best way beyond weighing it empty first.

Pretty sure they filled me up about half way today while I waited for it. It was way too light or I had testosterone shot in my coffee this morning :thumbdown:

Without a scale or taking the extractor off and visually inspecting, your screwed dood. Man do I wish you lived out here. That would be one of a great many less probs you would have. The U of A cryogenics dept is awesome and .82/L ftw.

thought so, shiat lol

hard to prove then. I will have to keep track of what I used. Dewar shouldnt loose more than half a liter per day new so....

Will be going with airgas as soon as im done commuting :D

I've seen guys quit after it starts splashing out the top, especially if dispensing at a high rate. The knowlegable one's will slow down the flow to get a complete fill.

I put mine in a scale it was 35lbs empty when I filled it up was like 94lbs if I remember right, but im down to 64lbs. I think I used like 10-14L

great thinking, mostly likely what this guy did :eek: wasnt the usual one

In my case I back up to the station with my truck and unload the dewar there...saves both of us from lugging it far. We both stand there and shoot the shit while it is filling.

Mines got wheels ftw! :D and no more stairs. I usually drop it off in the morning then pick it up on my lunch.

Same thing I do.

In fact, that little turnbuckle screw thingy broke off of mine, so I have to use a rachet and socket to open and tighten down the collar. Since he doesn't want to deal with that I have the job of taking off and putting the dispenser and collar back on - birds eye view if he's trying to screw me :D PS. Quarter inch course thread nut fits the turnbuckle perfectly :thumbsup:

Yeah Splig, those dollys with wheels are cool, I still got stairs to deal with though

omg! that's GREAT thinking!
i monna do that when i go fuel next week or so :thumbsup:
