Any way to figure out how big an hpa tank is?

[xboxandpb]

Is there a magic formula to find out how much air (ci) a tank holds by its dimensions. It does not state how big it is on the tank.

It should state it... take a picture of the label

hm, my tank doesnt say the size either.

Its very easy to tell the difference between them, take a pic of the tank next to a ruler too...

Length is 11" and 3" wide.

hmmm put it in some water and see how much it displaces...
i dont know but who makes it?
It looks kind of old. just buy a new one if you can afford it .
are you sure it not an old co2 tank?

[xboxandpb]

Its not a co2 tank, it was just hydroed and holds air just fine. Its made by Catalina Cylinders with a crossfire reg. Just want to know if there is any way to tell how much it holds.

Catalina usually stamps the info either on the top or bottom of the bottles. It almost looks like one of their 9000 series specialty tanks. Check out their products found at http://www.catalinacylinders.com/. If your not sure; try sending their tech support an email with the picture and any stamped markings.
