Valve Calibration Liquid
K FACTOR 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.
