and click “eq.
settings” button You will then access a submenu in which you can set the parameters below.
K Factor
K Factor is the number of pulses per unit volume, i.e. 1000 pulses/Unit. The meter’s tag would normally
indicate the K Factor.
Meter Factor
Meter Factor is a correction to the K Factor for this individual meter, applied multiplicatively to the K
factor.
Flow Cutoff Frequency (0-99)
The SFC332L Flow Computer will quit totalizing, when frequency is below the set limit. This feature is to
reduce extraneous noise appearing as data when the meter is down for period of time. The totalizer will
stop totalizing when the turbine frequency is below the limit.
Mass Pulse
Enter ‘1’ to select mass pulse input in LB.
Retroactive Meter Factor
If zero is selected, the meter factor will not apply to the entire batch. It will only apply from the time the
new meter factor is entered. Retroactive meter factor, on the other hand, will apply to the entire batch and
the entire batch is re-calculated, using the new meter factor.
Gross Include Meter Factor
Enter ‘1’ to include meter factor in gross flow.
Linear Factor
Enter the different correction factors for the meter at different flow rates. The flow computer will perform
linear interpolation. Notice that even though using this feature to enhance the measurement accuracy,
performing audit trail on a linearized meter factor is very difficult.
