<p>Hi Marc, <br>
</p>
<p>Thanks for the precision, <br>
</p>
<p>that exactly what I needed as information. 500 cc/ min is more
than we need <br>
</p>
<p>Best regards <br>

Thanks for reviewing the documents. The flow rates for the Dwyer
RMA - 12 and 13 (flow meters listed on the parts list) are given
in flow per minute. For example, George has FMV1 to FMV4 at 500
cubic centimeters, this would be 500 cc per minute.

Thanks for the work done. I think it is pretty consistent
with the discussions at the few meetings we had before. I
just verify (see attached) that the scheme would satisfy the
most demanding GEM layers of the SBS experiments. Which is
good.

I just have one technical question about the flow-meters and
transducers specifications. When you have numbers like 500
cc, 750 cc and 1000 cc, what does it mean exactly about the
maximum capabilities of these devices?
<br>
</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;
font-size:12pt; color:rgb(0,0,0)">
I am asking that because 1000 cc = 1 L basically and for
example one of the UVa GEM module (not layer) has a capacity
of 5 L and will run at a minimum of a volume change per hour
which means 5000 cc / hour so if the FM and FT are specified
to 500 cc, what does that mean? Similar concern for the INFN
layers.<br>

Can we run safely at these flow rates with these devices. It
is just a naive question from me to understand the numbers
because I am ignorant of big gas system like this, I am not
challenging the choices

George has completed the preliminary P&I for the
distribution panel and a components list (see
attachments). If everyone can take some time to review
the documents and provide comment, we can move forward
with mechanical drawings and procurement. If all
interested parties can send comments to this email

to have a discussion.</div>
