co2 tank with no tare markings

[Swab]

Trying to figure how if I have enough co2 in my 10lb tank to push a couple of kegs at a party tonight. I've been using this tank for a while now, so think it's close to empty.

My tank currently weight 21.1 lbs (9.6 kg)

Markings are as per the attached images.

Thanks guys.

Do you have a dual-gauge regulator? What does it say for pressure?

Mine has green and red zones; currently mine reads just lower than the green, and I expect I have 2 or 3 kegs worth of gas left to push out beer.

Once you get to the top of the red zone you're running on fumes, with a 10# tank perhaps just enough to dispense one 5 gallon keg.

Take a look at this tank size table, maybe you can figure it out the tare that way.

This is the answer that I knew, but laziness was standing in the way of.

My 'travel' reg's high-pressure gauge is broken, just hooked that tank up to my kegerator gauge (which sit on a 20lb tank usually)

The 10lbr is showing pressure at the top end of the 'order gas' zone:

It's probably good, but I should probably borrow a backup tank to be safe (I can't get it refilled today as everywhere is closed)

Or take your 20# tank instead. I always schlepp that thing around
