Once the initial calibration number has been entered into the console, proceed to section 2.6.1.4 to fine tune the flowmeter
for maximum accuracy.
2.6.1.2. DETERMINING THE PRESSURE SENSOR INITIAL CALIBRATION NUMBER
The Pressure Sensor Calibration Number can be found by determining the "Gallons per Acre" rating for the type of nozzles
being used. First find the chart that represents the nozzle series you will use and the nozzle spacing of your boom. Then find
the nozzle size needed for the range of speeds and the rate needed. When the nozzle has been selected find the column of
nozzle ratings in "Gallons per Acre" at 10 MPH. Then, on the left of the chart, find the horizontal line representing the
ratings at 30 PSI. Where the column and row intersect you will find the "Gallons per Acre" rating of your nozzles at 10
MPH and 30 PSI. This is the value to enter into the console as the pressure sensor Cal. #. For example, in the following chart,
for a floodjet K-SS10 nozzle, the row for 30 PSI and column for 10 MPH cross at 26.0 gallons per acre, the pressure sensor
cal. number for this particular nozzle.
NOTE: We recommend that these tests be done using water, and only after neutralizing the tank and system.
