Understand data summation

Values calculated for each accumulator record are summed for the virtualflowcomputer record that the accumulator records belong to.

• Gross Standard Volume (GSV) counter (Virtual Flow Computer [VFC]) = ΣGSV counter (accumulator)

• Indicated Volume (IV) counter (VFC) = ΣIV counter (accumulator)

• Flow rate (VFC) = ΣFlow rate (accumulator)

• Net Standard Volume (NSV) is calculated from the GSV by removing the volume due to sediment and water percentage:
