About the processing flow of validation routines

The meter validation processing takes place at different times depending on what is being validated. For example, the field-based equipment checks are done before the calculations that Measurement performs on the raw data that it receives. Additional checks are performed after any data calculations have been completed.

Meter Pre-Calculation Validation Routines

Note: These validation routines are performed before the Measurement application processes the data. The data is validated in its raw state.

• Low Flow Check

  Note: If pre-calculation validation fails for the Low Flow Check, post-calculation validation will not occur on the record. For more information, refer to Low flow check.

• Operational Limit Check

• Split Record Check

• Missing Parameter Check

• Flow Extension Check (performed on Orifice Meters only)

Meter Post-Calculation Validation Routines

Note: These validation routines are performed after the Measurement application has processed the data.

• Downloaded Gas Quality (GQ) Check

• Volume Ratio Check

• Host Calculated Energy vs. Remote Terminal Unit (RTU) Energy Check

• Reasonability Checks

• Operational Limit Check

• Frozen Data Check

• Low Flow Check

• Historical Average Check

• Rate of Change Check

• Beta Ratio Check

• Irregular Meter Overlap Check

• Lagged Alternate Check

Gas Quality Validation Routines

• Missing Parameter Check (+ Estimate)

• Reasonability Limit Check

• Operational Limit Check

• Frozen Value Check

• Historical Average Check

• Split Record Check

• Combined CO2 and N2 Check

• Combined C5 Plus Check

• Daily vs. Averages Check

• Lagged Alternate Check

Meter Daily Granularity Validation

Note: These checks are performed on daily data to validate data that is not at the Primary History Granularity (PHG).

• Daily Reasonability Checks

• Frozen Check (Daily Granularity)

• Daily vs. Aggregation

Meter Hourly Granularity Validation

Note: These checks are performed on hourly data to validate data that is not at the PHG.

• Hourly Reasonability Checks

• Frozen Check (Hourly Granularity)

• Hourly vs. Aggregation
