Smart Flow Settings for Venturi Pumps
Smart Flow mode can be used with all spray guns that use venturi-type
pumps, except for Tribomatic guns. It cannot be used for Prodigy or Encore
HD pumps.
When Smart Flow mode is selected on the Guns Configuration screen, the
air flow slider controls on the Gun Control screen changes to the controls
shown in Figure 5-6. Refer to Section 3, Standard System Configuration .

Flow Air %: Sets the powder flow rate. The range is 0 − 100%. The actual
percentage range available varies depending on the total air setpoint and
the maximum and minimum outputs for flow and atomizing air.
Total Flow R : Total Flow sets the velocity of the powder flow. The range is
2.55 − 10.2 M
3
/HR, minimum 0.17 M
3
/HR increments, or 1.5 − 6.0 SCFM,
minimum 0.1 SCFM increments. Powder velocity is inversely related to
transfer efficiency; the higher the velocity the lower the transfer efficiency.
Set the Total Flow setpoint first to obtain the desired pattern size and
penetration, then set the Flow Air % setpoint for the desired powder flow.
NOTE: If Total Flow is set to zero, the Flow Air % setpoint cannot be set to
anything but zero, and powder cannot be sprayed. To set Flow Air %, set
Total Flow to a value greater than zero.
Smart Flow Tables
See Tables 5-3 and 5-4 for examples of possible Smart Flow settings and
their equivalents in Atomizing and Flow-rate Air pressures and flows.
Figure 5-7 shows the effects of changes in Total Flow and Flow Air %
settings.
The Smart Flow tables provide a range of possible Total Flow and Flow Air
% setpoints. Read across to the vertical axis for the equivalent atomizing
air flows and pressures. Read down to the horizontal axis for the equivalent
flow-rate air flows and pressures.
