Type: Target 1 
Specific: Cooling 
Subject: T1 & T2 Target Water Flow Transducers Serviced 

 The target water outlet flow transducers on the T1 and T2 cooling packages were serviced (new shaft, paddle wheel, & o-ring) to address a noisy signal.  The service corrected the noisy signal.  Additionally, it appears the worn parts were causing the transducers to read high, as both dropped approximately 1 gallon/minute after the service.  Both transducers would occasionally trip the high flow warning (8.5gpm), and should now no longer do so.

A plot of the water outlet flows before and after the service is attached.  Cyclotron fault report #6086 was returned.
