Fluid Metering Assembly Overview
Pneumatic Fluid Metering Assembly
The fluid metering assembly in F
. 5 can be attached to
an automation arm, or mounted on a pedestal. Main
components of the fluid metering assembly are:
•
PrecisionFlo LT pneumatic fluid regulator (A)
•
Optional flow meter (B) to precisely measure the
amount of fluid dispensed
•
Solenoid air valve (C) that controls a dispense valve
•
Voltage to pressure (V/P) controller (D) for adjusting
the air pressure to the fluid regulator (A)
PrecisionFlo LT Pneumatic Fluid
Regulator
The PrecisionFlo LT pneumatic fluid regulator is a preci-
sion fluid pressure regulator that uses air pressure to
control fluid pressure and to provide fast response to
electronic commands and ensure a precisely controlled,
continuous flow of material.
The PrecisionFlo LT module combines continuous pres-
sure control with the ability to change bead profiles
quickly. When used with one of the optional flow meters,
the PrecisionFlo LT module automatically adjusts for
fluctuations in the operating environment, such as mate-
rial viscosity, temperature, tip wear, and automation
speed, while maintaining the desired dispense rate. The
module responds to automation-supplied signals to pro-
vide an accurate and consistent output flow based on a
comparison of actual to desired flow rates.
