CO2 high pressure gauge help

Hello all, just recently noticed yesterday, March 25, 2019 that when the solenoid is on and CO2 is running the pressure is about 550 PSI and when the CO2 is not running the PSI is about 750. Is this normal? 1st pic is on, 2nd is off.
I just saw this happening yesterday and it never happened since I set it up. I've checked for leaks and wasn't able to find any at all. I will have to double check tonight. I just set this CO2 tank up March 1st.

Yes it is. The gauge is reading an instantaneous pressure at the base of the gauge. When there is flow through the system, there is a pressure drop. Depending on temperature, exact inclination of the tank, the level of liquid in the co2 tank, etc etc that reading will vary. When the flow stops, after stability you will be reading the mean vapor pressure of the tank.

Always room for a good difference of opinion?
In my view, this is not normal as the high pressure will only vary a bit with radical changes in tank temperature or when the liquid CO2 has all gassed off and you are working on the remaining fumes which I might guess would last a few days to a week if I am correct on seeing a five pound tank.
I would check to see that it is happening each time the solenoid closes, not just one time as a 200 PSI change is more than I would expect. I would also want to do a really good soap check to verify that there is not a leak and most of the tank is now gone.

I have 2 of those c02Art regulators and have never experienced that issue. You may want to reach out to c02Art, their customer service is second to none.

I have this same model regulator from co2art. I will unplug my solenoid when I get home today and see if that changes the pressure reading on the gauge. On mine, that gauge has been really accurate. As the tank starts drying out, the needle actually gives me a pretty accurate indication of how much co2 is left in the tank.

I'm guessing this may be one of those cases where we have folks drop in to ask for a solution but never hear back. Too bad as this sounds like an interesting point.

CO2 high pressure gauge help

Sorry for the late reply. On my regulator, unplugging the solenoid makes the pressure increase marginally, probably what equates to 20-30 PSI. Itís very small, unnoticeable without actually watching the needle.


Edit: Upon further pondering this matter, I would suspect you have a leak somewhere post regulator. Do a soapy water test (Dawn is mild and very safe). If that doesnít yield any results, ensure that your tubing is connected very securely to the diffuser. You want all of the co2 going through the system with no leaks anywhere.
