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 sys-
tem automatically adjusts for fluctuations in the operat-
ing environment, such as material viscosity,
temperature, tip wear, and automation speed, while
maintaining 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)
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 communi-
cation to the fluid plate assembly.
Fluid Plate Assembly
The fluid plate assembly contains components that con-
trol 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 sup-
ports up to 16 dispense valves and can simultaneously
dispense from up to 10 dispense valves.
