Integrated Flow Control
Flow Control Description
Flow control is an optional feature which incorporates an
intrinsically safe regulator control module with the Pro-
Mix 2KS automatic system. Flow control precisely regu-
lates the flow of material to a manual or automatic air
spray gun, to help ensure adequate coverage and avoid
sags or runs in the finish coat.
NOTE: Flow control cannot be selected with dynamic
dosing. It is not for use with air-assisted or airless spray
guns.
Flow control uses the existing flow meters in a wall
mounted fluid station or a RoboMix fluid station. There is
no flow meter in the mixed material line.
Flow Control Components
249849 Flow Control Module
See F
IG
. 71. The 249849 Flow Control Module includes
an air-operated fluid pressure regulator, fluid pressure
sensor, voltage to air pressure valve, and circuit board.
See manual 3A2097. The function of this unit is to
receive the flow analog signal and drive (manage) the
desired flow rate.
24H989 Flow Control Module
See F
IG
. 72. The 24H989 Flow Control Module is for use
with a user-supplied, remotely mounted, air-operated
fluid pressure regulator. The module includes a remote
fluid pressure sensor and connecting cable, voltage to
air pressure valve, and circuit board. See manual
3A2097. The function of this unit is to receive the flow
analog signal and drive (manage) the desired flow rate.
NOTE: For best results, place the supplied pressure
sensor as close to the remote fluid regulator as possible.
