Hi Jack and Brad,

We want to confirm with you on the flow sensor specifications for the SBS/BB GEMs. We have ordered 20 high flow sensors (750 sccm) for the front tracker layer GEMs and 100 standard flow sensors (400 sccm) for the back tracker layer GEMs.

For the front tracker flow sensors we have ordered 20 units to handle the supply (6 required) and exhaust (6 required) with the balance used as spares (8 count).

For the back tracker flow sensors we have order 100 units to handle the supply (44 required) and exhaust (44 required) with the balance used as spares (12 count).

Please acknowledgement, and I will contact the vendor to complete the order.

Regards,
Marc
