• The split vent has a 1/8-in Swagelok threaded fitting. Create
and use a 1/8-in tube adapter (as shown below) to convert
the 1/8-in threaded fitting into a 1/8-in tube. This prevents
the rubber flowmeter tubing from leaking around the
threads, which will result in leakage and thus an incorrect
flow reading.
• The septum purge is a 1/8-in tube. Use the red rubber
adapter shown to measure flows.
