<div>Hi Youri and Nick,<br>
</div>
<div><br>
</div>
<div>We met a couple of weeks ago and discussed a better strategy
to supply <br>
CO2 to the detector in the hall. Currently, we use a mass flow <br>
controller, which in the case of an outage which would outlast
the UPS <br>
would close. The solution is to change this to a mass flow
transducer on <br>
the detector inlet, which would be supplied by a standard
rotameter <br>
installed in the gas shed. This set up would then supply gas in
any <br>
condition and still be adjustable without entering the Hall.<br>
</div>
<div><br>
</div>
<div>The rough estimate for the new equipment would be
approximately $3200 <br>
which would include one transducer, plus a spare, and a
rotameter. <br>
George is preparing an dollar figure quote and augmenting the
drawings.<br>
</div>
<div><br>
</div>
<div>Once you receive the quote from us, please let us know how to
proceed <br>
with the procurement as soon as possible.<br>
</div>
<div><br>
</div>
<div>Thanks,<br>
</div>
