Default Litre/min(Cuft/hour) to psi conversion ?

I picked up an inexpensive regulator from Harbor Freight for my back up CO2 tank but the low pressure gauge reads in Litre/min(Cuft/hour). Is there a conversion to psi for this or do I need to replace the gauge.

It sounds like you have a flow meter, not a regulator.

No there is no conversion.

OK so no conversion from Litre/min(Cuft/hour) to psi. Do you think that replacing the gauge to psi would work?

This is a link to the item

If it is a flow gauge it will not function properly as you intend. If you change the gauge To psi and set it for 10 psi, it will come out at 10 psi but never stop flowing. You will probably blow up a keg if it's left attached.
