SYSTEM CONFIGURATION / 81
LIQUID FLOW CALIBRATION
To determine the actual K-Factor of a system, water should be dispensed
through the system and measured. The calibration procedure will
accumulate the pulse. At the end of the calibration procedure, the operator
enters the amount dispensed. This number becomes the actual K-Factor
instead of the one stamped on the flow meter body.
One of two methods can be used to measure the gallons of liquid flowing
through the sprayer system. The more liquid passing through the system
during calibration increases the degree of K-Factor accuracy.
Method 1 100% Catch Test:
This is the recommended method because a larger volume of liquid passes
through the entire sprayer system making errors in weighing a smaller
factor.
1. Fill the tank and weigh the load.
2. Activate the calibration routine.
3. After spraying a few hundred gallons but before the load is empty, stop
the calibration.
4. Weigh the load again.
5. Calculate gallons dropped.
Method 2 Partial Catch:
1. Use a container such as a bucket or barrel to catch all liquid.
2. Weigh empty container.
3. Weigh container with liquid.
4. Calculate weight of the liquid (weight of full container minus empty
container).
5. Calculate gallons dispensed.
6. Calculate % of total volume caught.
7. Gallons dropped/% caught.
Method 3 Nozzle Flow Meter Test:
1. Use measured catch container.
2. Set target flow rate.
3. Enter # of nozzles of complete channel.
4. Catch volume dispensed from nozzle in 1 minute.
5. Catch multiple nozzles.
6. Average the volume caught from the collected nozzles.
7. Enter average value.
INITIATING A LIQUID FLOW CALIBRATION PROCEDURE
1. From the Channel Setup screen, press the K-Factor Calibration
button.
2. Set the Target Flow Rate and Target Ground Speed which will
calculate the operation rate.
3. Press the Start button to initiate flow calibration procedure.
4. Press Stop when container is full.
5. Enter amount (gallons) dispensed in the Total Amount Collect field.
6. Press Save button to accept the selection.
