Weighted average calculations for a Batch Transfer

Weighted average values for Batch Transfers reset with every new batch.

To calculate a weighted average flow rate, the system sums the weighted average flow rates of the Batch Transfer Sources:

To calculate a weighted average Meter Correction Factor (MCF), the system uses the Indicated Volume (IV) as a basis for aggregating the weighted average MCF's of the Batch Transfer Sources:

To calculate a weighted average for Temperature (T), Pressure (P), Observed Density (OD), Corrected Density (D), Correction for Temperature of a Liquid (CTL), and the Correction for Pressure of a Liquid (CPL), the system uses the Gross Volume (GV) as a basis for aggregating the weighted averages of the Batch Transfer Sources. GV is the actual volume at flowing temperature and pressure after being corrected by the meter factor.

Where Y is one of the following: Temperature (T), Pressure (P), Observed Density (OD), Corrected Density (D), Correction for Temperature of a Liquid (CTL), or the Correction for Pressure of a Liquid (CPL).

To calculate a weighted average for Viscosity and Sulphur, the system uses the Gross Volume (GV) as a basis for the calculations. The following procedure is used:

Where Y is Sulphur or Viscosity.

To calculate a weighted average Sediment and Water Percent (S&W), the system uses the Gross Standard Volume (GSV) as a basis for the calculations. The following procedure is used:
