FYI, the flow currently used in EEL rm 125 was 500 sccm. Was this
too high?<br>
<br>
For 2 cc per sec is 120 sccm. You would want, at a minimum, 0-300
sccm, so the reading is in the middle of the operational range.<br>

Aalborg part# PMR1-011387, $168, 0-300 sccm/min N2 range<br>

<div class="moz-cite-prefix">Dear George,<br>
is there any models down to ~500sccm/min (or lower)? <br>
The flow meter we bought has a sensitivity well below.
Considering we are expecting ~1-2 cc/sec (say 1-2 bubbles per
second) we should get about 60-100 sccm/min and with a low
precision gauge it's very possible we can not measure it.<br>
Thanks in advance<br>

I recommend this flow rotameter, Aalborg part# PMR1-013465,
$125, 0-2000 sccm/min N2 range, for the N2 purge circuit. This
item can be purchased online using a credit card.<br>
