To anyone who may have come up against this problem: On my Coulter
EPICS Elite  I have an INNOVA 305  Argon Ion laser, only  about 100
hours on it. The water flow to the power supply  via  a new filter is
about 3.5 gal/min (verified  by measuring flow rate by volumetry).  In and
out flow to and from the power supply is correctly hooked up,  I know it
can cause problems if it is hooked up in reverse. The filter is not clogged,
the  hose is not crimped.  Still the  remote control display   registers 0
flow,  consequently  the laser cannot be powered up. Did anyone out
there  encounter this problem?  While I am in touch  with Coulter,  maybe  
someone  knows,   Is there a valve or a flow  activated switch that got
stuck? Thanks  for any advice. Peter Bercz, USEPA/NERL EERD
