Measurements of tanks?? How much oil in tanks?

I was looking for a 400 bbl chart also but couldn't find one. Here is one I made up. Hope it helps someone. http://postimg.org/image/x63lmoo9t/

 

Havent gone through reading responses but basically on a 20 foot tall, 400 barrel upright 1 foot is 20 barrels and 1 inch is 1.67 barrels. The math to figure out anything else is pretty simple involving those.

 

Baby powder on your gauge. Gives you a good clean line where the oil is.

To better see the liquid level on a gauge line, use baby powder or gauging paste.

If your gauge line has a black strip along the bottom, hold it so that the sun is reflecting off the black strip. This will make it easier to see the liquid line.

If you're gauging at night, use a headlamp (or flashlight) with red light to read the gauge line.
