2) Using the Pump Setting Number determined in "CALCULATING PUMP SETTING". Locate the
METER CAL number that corresponds to this setting.
EXAMPLE: For Pump Setting 5 the METER CAL number is 220 [744].
3) Write down this METER CAL calibration number for future reference when programming the
Console.
4) If two injection pumps are used, determine the METER CAL for remaining Injection Pump.
4. CALCULATING PUMP SETTING
The following procedure calculates the correct Pump Setting for Injection Pump. The High
Volume Injection Module has an output range of 2.5 to 200 oz/min, use Figure 12A. The Low
Volume Injection Module has an output range of 1.0 to 100 oz/min, use Figure 12B. The Ultra
Low Volume Injection Module has an output range of .5 to 40 oz/min, use Figure 12C.
1) Calculate MAXIMUM and MINIMUM volume per minute (oz/min)[dl/min] of product required by
using the following formulas:
MAXIMUM vol/min = Speed x Boom Width x Rate
5,940 [60,000] {137}
Speed = Maximum Spray Speed in MPH [km/h]
Boom Width = Maximum Number of Spray Nozzles x Nozzle Spacing in inches [cm]
(i.e. total boom width)
Rate = Recommended Product Application Rate in Ounces per Acre
[dl/ha] {oz/1,000 sq. ft.}
MINIMUM vol/min = Speed x Boom Width x Rate
5,940 [60,000] {137}
Speed = Minimum Spray Speed in MPH [km/h]
Boom Width = Minimum Number of Spray Nozzles x Nozzle Spacing in inches [cm]
(i.e. one boom width)
Rate = Recommended Product Application Rate in Ounces per Acre
[dl/ha] {oz/1,000 sq. ft.}
EXAMPLE: Maximum vol/min (High Volume Pump)
US (ENGLISH UNITS)
Speed
= 15 MPH
Boom Width = 36 nozzles x 20 inches/nozzle = 720 inches
Rate = 2 pints/acre x 16 oz/pint = 32 oz/acre
Maximum oz/min = 15 MPH x 720 inches x 32 oz/acre = 58.1
5,940
SI (METRIC UNITS)
Speed
= 24.1 km/h
Boom Width = 36 nozzles x 51 cm/nozzles = 1836 cm
Rate = 2.3 lit/ha x 10 dl/liter = 23 dl/ha
Maximum dl/min = 24.1 km/h x 1836 cm x 23 dl/ha = 17.0
