How much pressure in the tank

[Highrise]

I have a 78cuft 4,500 psi Carbon Fiber tank with one guage.

How do you figure out how much pressure is in the tank.

When i go to fill the gun, the guage reads the pressure being placed into the gun, but i have no way of knowing whats left.

There has to be some way to read tank pressure,?

thanks for the help

Two way of knowing pressure inside the tank.

1. Install a valve that have both gauges to read tank pressure and output pressure.

2. Plug a stopper at the end on the line. And open the tank. It will tell what's left in.

Imo it's always best to have a valve that reads both so don't need to keep plugging a stopper and opening tank every time to check.

Buying a different fill valve with 2 gauges is more expensive then a 'dead head' for the hose. Plug in the dead head and open the valve, Thers yoiur pressure. There other retailers but if you call 'airtanksforsale'. (Joe B), you can get all the info.

I have 3 tanks... 2 have 2 gauges but I hardly ever flip them over to look at the other gauge (tank pressure). So really, for me, they are an excess. As I see the a tank just barely fill a gun, I know I need a fill. Circumstances vary. Going back a few years I had easy access to 4500 psi fills. That source is gone. So rather than drive much further (2x roiund trips for each fill) I bought a compressor. Not bragging, just saying that my view might be skewed….

If you simply want to see current pressure, a dead head is the easiest way.
