NOTE: Periodically calibrate the flowability meter using plain water. Water should flow
through the orifice such that the time between the top line and the bottom line is 32
±
2
seconds.
Once the flowability of the liquid has been measured, Tables 1 and 2 can be used as an
approximate guide for setting the Flow Control Orifice size for your spray application.
Flow Rate Chart
NOTE: THE FLOW RATES SHOWN
HIGHLIGHTED WILL PRODUCE DROPLETS OF
20 MICRONS (VMD) OR LESS (ULV). USING
FORMULTIONS WITH HIGHER VISCOSITY THAN
32 SECONDS WILL REDUCE THE FLOW RATE
BY APPROXIMATELY 20% OR MORE.
WARNING
ALWAYS APPLY FORMULATIONS IN ACCORDANCE WITH THE
MANUFACTURER’S RECOMMENDATIONS
.
The flow rate in the Tables 1 and 2 are the average value of several machines tested,
with the nozzle located at the level of the machine base.
The Dyna-Fog
®
Microtec™ Nozzle will produce 90% of the droplets below 20 microns
(ULV) when used at the recommended flow rates. This meets the requirements of all
current chemical labels for controlling flying insects.
When the high flow rate is discharged through a single nozzle the Twister™ XL will
produce larger droplets of 50 microns suitable for applying a residual deposit to
vegetation and any other surface.
NOTE: Always handle and dispose of all chemicals in accordance with the
manufacturers’ instructions and the material safety sheet for the chemical being used.
