To determine the calibration number for a specific gravity that does not
appear in Chart A simply multiply the specific gravity of the resin by 9.5280
for a VLS-4600 pump and by 24.576 for a HVLS-1000 pump.
Example: 9.5280 x 1.08 = 10.290
NOTE: The resin calibration number is based on one count per stroke.
With the sensor assembly used there will be more counts per stroke.
To adjust the calibration number divide by the number of counts.
Example if there are two counts per stroke divide the divide the
calibration by two. You can also divide the 9.5280 by the number of
counts for the VLS-4600 and divide 24.576 by the number of counts for
the VLS-1000.
