Hi George,<br>
we have re-discussed the positioning of the different components of
the FTCal gas system with Bob and Morgan, who is helping us with the
installation. Their suggestion was to possibly keep everything on
the subway, pacing the rotometer close to the other ones already
installed and the bubbler in the bubbler tray with the other ones.
Could we move the flowmeter upstairs as well: I thought that was not
going to be possible but we check the cable from the cRio to the
device and that looks long enough.<br>
If you are available we could meet to discuss it: we will be in the
Hall most of the day tomorrow working on cabling.<br>
Best regards,<br>
Raffaella<br>

Hi George,<br>
thanks for pointing out that the rotometer has to be upstream. I
guess this was not considered when the new configuration was
discussed and the idea of moving rotometer and bubbler on the
subway was just for convenience. However we can go back to the
original idea of having everything close to the compact rio. We
will revisit the plan and get back to you on Monday.<br>
Regards,<br>
Raffaella<br>

<p>The flow control rotameter should be upstream of the
transducer if your concerened with accurate transducer
readback. It could be right next to it, The flow control
rotometer must be in the vertical position. Have you discussed
these changes with the DA?</p>

Hi George,<br>
plans about the panel have changed a bit: it was decided to
install rotometer and bubbler close to the detector on the
subway, leaving the flowmeter close the compact rio since I
believe it gets power from the compact rio. <br>
Thanks,<br>
Raffaella<br>

I can hook it up and make a temporary mount of some sort. I
thought the FT group was working on a N2 panel?<br>

Could you connect and mount the FT flow meter today?
Thanks,

Hi Amanda,
We have installed the nitrogen lines for the ftcal purge. The still have to be connected to the main line in the hall but they are ready to be connected to the flow meter. Will you take care of that?
Also, the flow meter is now sitting on the floor but it would be nice to have a small panel to attach it to the rack . Would that be possible?
Thanks ,
Raffaella
