Usually in a sealed tank, the switch contacts are in the tank too. The SF6 gas quenches any arcs that form when the switch contacts are opened.
A CO2 tank does not necessarily have to be upright. It depends if you want liquid CO2 or gaseous CO2. When I purchased a CO2 tank for a specific application, namely, CO2 snow cleaning, I had the option of getting a tank that either had a dipstick, that picked up liquid CO2 from the bottom of the tank, or one that had no dipstick so that it collected gas from the top of the tank. I selected a tank without the liquid pickup. So, my upright tank output gas. However, if I wanted liquid CO2, I would put my tank slightly upside down, and get liquid CO2. It is probably not recommended to run a commercial gas tank in a non-upright position. So, depending on what type of tank you have, and what type of output you want, the answer to your question literally is: depends. For farm and garden use, you are probably seeking gaseous output, and probably have a tank with no dipstick; based on these assumptions, yes, you will need to keep your tank upright.
Probably the most common reason for this is that the capacity of something has a major impact on where it can be located to begin with. For instance, you couldn't fit the normal size 70 Liter capacity gas tank under the hood of your car, because the engine is there and there isn't room for the tank as well.
You can use a fuel tank additive called "Heet." Basically, Heet is a type of alcohol which mixes with the water in your tank and allows your engine to burn it. Depnending on the amount of water the tank could need removed or drained.
I have fixed a couple over time and what I do is fill it with water and detergent empty it out Then do it again, then Weld it.
