System Overview

The PCF fluid metering system combines closed-loop
pressure control with the ability to change bead profiles
quickly. When used with an optional flow meter, the
system automatically adjusts for fluctuations in the
operating environment, such as material viscosity,
temperature and tip wear, in order to maintain the
desired dispense rate. The module responds to
automation signals to provide an accurate and
consistent output flow based on a comparison of actual
to desired flow rates.
Typical Applications
• Bead dispensing
• Gasketing
• Seam sealing
• Hem flange
• Sound deadening
• Anti-flutter
• Body panel reinforcement
• Profile wrapping
• Cable filling

Control Center (User Interface)
NOTE: The control center is available with or without an
ADM, depending on the model you are using. See
Models on page 4.
The control center communicates with the PCF fluid
plate assembly to control fluid pressure and dispense
valve operation.
The control center receives input from the automation
controller, and uses these inputs to determine
communication to the fluid plate assembly.
Fluid Plate Assembly
The fluid plate assembly contains components that
control and monitor fluid dispensing. A PCF fluid
metering system can have up to four fluid plates. Each
fluid plate can control up to four dispense valves. The
system supports up to 16 dispense valves and can
simultaneously dispense from up to 10 dispense valves.
PrecisionSwirl Orbital Dispenser
(Swirl Dispenser), Sold Separately
The swirl dispenser dispenses material in a circular pat-
tern at speeds from 6600 to 24000 rpm. A PCF fluid
metering system can have up to four swirl dispensers.
See manual 309403 for detailed information.
