    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. FWIW, the Mouse has been holding 30psi as part of my CO2 leak testing now for several days.

    It is a pretty simple device: the valve is periodically opened to permit passage of a tiny amount of CO2, akin to a "bubble", and the frequency of opening is adjusted by a knob, all of this managed by a simple

    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! :)

    Of course there's nothing to say you can't put a bubble counter on anyway!:cool:
