Meter Cal Tag
NOTE: All volumes will be displayed in pounds [kilograms] of actual nitrogen. To properly control the
application of anhydrous ammonia, enter the target application rates as pounds [kilograms] of actual
nitrogen per acre [hectare] or lbs(N)/acre [kg N)/ha].
NOTE: If meter cal tag does not have meter cal number in "Lbs of N" use the following formulas to adjust the
original meter cal for the desired display preferences.

ADJUSTING VALVE CAL

Refer to the console Installation and Operation Manual for instructions on entering or adjusting the valve cal.
NOTE: The valve cal may need to be adjusted to speed up or slow down the valve to obtain desired results,
particularly in applications using low flow rates.
RECOMMENDED STARTING VALVE CALS:
Vortex Fast Valve: 743 (If too slow try 643 or 543)
Vortex Two Valve: 2123 (If too slow try 2223 or 2323. If low-rate control is unstable, try 2133 or 2143)

ADJUSTING RATE CAL

Enter the target rate in actual pounds of nitrogen (N) per acre [kilograms per hectare].

Meter Cal Gal / 4.22 = Meter Cal Lb N
Meter Cal Liter / [0.506] = Meter Cal Kg N
Example: 720 Gal / 4.22 = 170.62 Lb N
Example: 190 Liter / [0.506] = 375.494 Kg N
