I haven't had any luck, and I'm assuming it's probably not something that exists, but are there any dual solenoid regulators out there? Not just a splitter with one, but two; so, for example, you could have not only one bottle feeding two tanks, but have one bottle feeding two tanks at different times.
And input would be awesome, thanks!
EDIT: Huh... you know I was just looking at my regulator, and it struck me... I had it set up body > solenoid > splitter > valves > bubble counters - Can't I just go body > splitter > solenoids > valves > bubble counters?
