<div>Hello Bob,<br>
</div>
<div><br>
</div>
<div>DSG has rotameters and flowmeters on hand to upgrade RICH's
nitrogen supply panel to increase the maximum flow it is
capable of. Attached is George's system diagram showing the
upgraded panel and his Excel sheet listing all hardware that
will be used.<br>
</div>
<div><br>
</div>
<div>Because you are system owner of RICH's gas system, you will
need to request and assign a Design Authority. We would need
the DA to approve the changes and determine the appropriate
orifice size for the upgraded panel.<br>
</div>
<div><br>
</div>
<div>Since we have the parts on hand, we would be able to
install the upgraded components on the panel as soon as DA
approval is given and the experimental run ends.<br>
</div>
<div><br>
</div>
<div>Best regards,<br>
</div>
