Preset Total
In Example 2, when the Take Flush From First Component is executed, the resulting product ratio is 50/50, since
the non-flush component was shorted (component #1). In this case, the desired 60/40 result would have been
achieved by using component #1 as the Line Flush Component.

ALIBRATION
Meter factors are determined during flow meter proving tests by comparing the observed volume with the volume
that is indicated on the MultiLoad II display. As the MultiLoad II collects pulses from a flow meter, it divides the
pulses by the K-Factor to obtain a Raw Gross Volume. Meter factors are used to correct the Raw Gross Volume
so that the volume indicated on the MultiLoad II display matches the volume that is observed during flow meter
proving.
Meter factors can vary significantly at different flow rates. For this reason, meter factors are determined for two or
more flow rates to improve accuracy over a range of flow rates. The Meter Factor Linearization feature permits
the MultiLoad II to interpolate a meter factor when product is flowing in between two flow rates that have proven
meter factors.
As product is delivered, the meter factor is continuously applied to the Raw Gross Volume to display the Gross
Volume. The meter factor that is applied against the Raw Gross Volume changes as the flow rate varies between
two established flow rates.
