Present:  Elliott W, Beni Z, Damon, Narciso G, Mark S, Hovanes E, Dave B, Josh B.


'''Gas System'''

We spent the entire (short) meeting going over the gas system drawings (see link above), and discussed safety issues, sensor choice, buffer tank size, power, installation, etc.  Dave B will do the PLC programming since Josh will be gone by then.  Note that all PID loops reside in Brooks controllers, none needed in the PLC.

Plan is for Dave/Josh and Beni/Narciso to agree on channel types and counts, and for Mark S to decide what power supplies and auxiliary equipment is needed.  Dave B will come up with a final PLC parts list and place the order.
