I have a Dennerle CO2 regulator with double manometers.
Each time I open my needle valve, the service pressure drops. If I close the needle valve, the working pressure increases. Thus, adjusting bubble count is very hard since working pressure variations significantely affect the bubble count (the higher the working pressure, the faster is the bubblle count). So, to increase my bubble count, I need each time to open the needle valve and than readjust the working pressure.
Is my regulator behaviour normal or is it a bad manufactured product. I thought working pressure should be fixed with its own dedicated valve and not being affected by distal pressure variations
Many thanks to clear this for me
