Ransburg RCS 2 Ratio Control System - Manual (Page 80)

Example:
300 cc’s (totalization screen value) X 305 cc’s (actual volume collected)
90909 (current pulse per liter value) New Pulse/Liter value
Therefore, New Pulse/Liter Value = 305 X 90909 = 92424 pulses/liter
300
Enter the new value for the Pump Pulses per Liter
value on the Configure Channel screen, send it
to the RCS-2 and retest. Repeat the test several
times until the accuracy required is obtained and
the values (actual volume vs. displayed volume)
are repeatedly very close to one another.
1 Note: In order to convert the weighed material
to a volume, the specific weight of the material
must be known. (Specific weight is defined as
the weight of the material per unit volume.) This
is normally available from the manufacturer of the
material. If this information is unavailable or the
material has been reduced, the specific weight will
need to be experimentally determined. Obtain a
very accurate measuring device such as a syringe,
pipette, 10 cc graduated cylinder, etc. and weigh
the container prior to filling it with material. Then
put exactly 10 cc’s of material in the container and
reweigh the container. Subtract the weight of the
empty container from the weight of the full one and
divide that difference by 10. The resulting value is
the material’s weight per cc. This value can then
be used to very accurately determine the volume
of material collected in the above tests.
