CONSOLE CALIBRATION
1. CALCULATING "METER CAL"
The Flow Meter calibration number is stamped on the tag attached to each Flow Meter.
This number is to be used for gallons [liters] per application.
To convert original METER CAL from gallons to desired units of measure, see METER
CAL CONVERSIONS on page 3 . Write down this calibration number for future reference
when programming the Console.
2. CALCULATING "LIQ CAL"
Determine the application rate at which your chemical should be applied. Consult
with your Dealer to ensure your spray nozzles are capable of applying at this rate.
In determining which spray nozzles to use, you must know:
1) Nominal Application Pressure ___PSI [kPa]
2) Target Application Rate ___GPT [lit/MT]
3) Granular Application Rate ___(lb/mile) [kg/km]
4) Target Speed ___MPH [km/h]
5) Number Of Nozzles ___
From this information you can than calculate the volume per minute per nozzle as
follows:
GPM = GPT x (lb/mile) x MPH
120,000 (No. of nozzles)
lit/min = lit/MT x [kg/km] x [km/h]
60,000 (No. of nozzles)
Use GPM [lit/min] and pressure to select appropriate tip from tip chart.
EXAMPLE: EXAMPLE:
EXAMPLE: EXAMPLE: EXAMPLE: 1) Application Pressure 30 PSI [200 kPa]
2) Target Application Rate 7.0 GPT [30 lit/MT]
3) Granular Application Rate 2900 lb/mile [800 kg/km]
4) Target Speed 6.2 MPH [10.5 km/h]
5) Number of nozzles 3
US UNITS US UNITS US UNITS US UNITS US UNITS GPM = 7.0 GPT x 2900 lb/mile x 6.2 MPH = .35 GPM
120,000 (3)
SI UNITS SI UNITS
SI UNITS SI UNITS
SI UNITS [lit/min] = 30 lit/MT x 800 kg/km x 10.5 km/h = 1.40 lit/min
60,000 (3)
Using CAPACITY = .35 GPM [1.40 lit/min] and pressure = 30 PSI [200 kPa] you would
select tip number XR8004 from the chart on next page, since it comes closest to
providing the desired output.
