The Accumulator (Accum) database contains aggregate volume and accumulator data collected in RealTime database (RTDB) rate table records.

Every hour:

  • Volume flow data from the rate table in the RTDB is retrieved.

  • Data is written to the Accum database in the Historical database.

  • The Integration Block of the rate table is reset.

The data collected from the rate table includes:

  • The raw accumulator count.

  • The adjusted accumulator value (the raw accumulator count converted to engineering units).

  • The data quality status.

  • The calculated volume for that hour (in engineering units).

    Note: The Accum readings are always taken from the last sample in the period.
