Hello;
I'd like to clarify my position in the question I asked yesterday.
I have no intention of getting rid of the bubble device, and I have no
intention of getting rid of P10. I use the system now with a regulator, a
needle valve, and the bubble meter. My needle valve is unmarked as to
range, and is really too coarse for fine control over the rate - with the
side effect that if you bump the needle valve knob the flow rate changes a
lot. My intention is to replace this with a finer control rotameter which
has the needle control valve and a visual sight gauge to let you know that
it's actually set correct. Since the JEOL spec doesn't actually say what
the flow rate is in l/min (or at least I can't find it) I figured I would
ask if anyone knew.
Have a nice day.
Best regards,
Steven Cogswell
