I have found the recommended Dwyer Flow Control Valve for $77.50 in Vancouver. This is controlled by the included needle valve and would replace the standard needle valve/bubble counter set-up. The availabe flow is between 5-50 CC/minute (there are higher amounts available, but Mr. Joshi recommends this one and is using 20 CC/minute).
What do you DIY types think?...The cost of a needle valve by itself is $27.00 and I am unsure what it will cost to make a bubble counter...tough to analyze/compare not having made anything like this before...any other comments? Cheers.
