    I'm working on an electromechanical needle valve based on a Clippard Mouse valve. At this point in time and probably forever it's strictly for my own amusement: I like building and tinkering. I figure I need a solenoid valve anyway to turn off CO2 at night, so why not have it perform as a realtime metering device as well.

    a bubble counter is also a good indicator of co2 system health, ime. It give you some visual control over how much gas is going into your tank. If something is abnormal, then chances are something is wrong with your system (e.g. leak, someone knocked the metering valve, etc.).

    keep us posted! :)
