<p>Yuri,</p>
<p>DSG has removed the flow meters and rotameter from the hall for
testing. The flow meters were used in the hall during the previous
run. After they are tested we will post results on the dsg-svt
mailing list.</p>

<p>Thank you Peter,</p>
<p>A comment on your statement on the flow meters. The models and
the number of the flow meters purchased (no spares) were defined
by the HBI group. I reported several times that this model is
not designed to work in magnetic field. The flow meters failed
the very first time the solenoid was turned ON. Please select a
model which would be compatible with requirements of the
detector and let me and Bob Miller know. <br>

testing the cooling system in preparation of the SVT for beam
operations it is critical to have measurements of the coolant
flow. Both flow meters observed issues with correct reading of
the flow. The flow meters have been disconnected from the
cooling lines (control lines are still connected). Please test
the flow meters asap. <br>

all the other work in Halls B, C, and D we are doing in
preparation for the upcoming run. <br>
Hall B SVT does not have cooling system repair components
(external to the chillers) which was first mentioned in our
email of 1/31/2017 (listed below).</font><br>
