Filter sizing
Filter information should be reviewed to confirm correct filter
sizing for the normal and the maximum viscosity case (in the
case of viscous fluids). Additionally, maximum filter collapse
pressure, internal filter cartridge design and cartridge sealing
design should also be reviewed at this time.
Instrumentation
All instrumentation should be reviewed to confirm proper se-
lection, materials of construction and proposed installation lo-
cations. All instrumentation loops should be reviewed to ensure
that critical instrumentation can be calibrated and maintained Fig 7.5.7 Console baseplate construction (Courtesy of Fluid Systems)
