System Overview

The PCF fluid metering system combines closed-loop
pressure control with the ability to change bead profiles
quickly. When used with the optional flow meter, the
module automatically adjusts for fluctuations in the oper-
ating environment, such as material viscosity, tempera-
ture, tip wear, and automation speed, while maintaining
the desired dispense rate. The module responds to
automation-supplied 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.
