General Gross Error Analysis Rules

Use the General Gross Error Analysis Rule to identify erroneous data before doing further statistical analysis on a case. The following table lists validation rules that can be run within the General Gross Error analysis.

General Gross Error Analyses

Type of ValidationAnalysis Rule
Tank ValidationTanks with a change of density between cases.
Tanks with no density/molecular weight/material.
Tanks with density comparison to default density.
Tanks with change of material between cases.
Tanks with invalid material names.
Tanks with change of temperature between cases.
Tanks with change of in/out of service or set to self-calculate.
Tanks with change of water level between cases.
Tanks with inventory change between Cases and have no inputs/outputs.
Tanks with no inventory change between Cases and have either inputs and/or outputs.
Tanks with zero measurement or tolerance.
Tanks with negative measurement or level.
Tanks with corrected measurement.
Tanks with measurement below minimum or above maximum.
Tanks with level below low alarm.
Tanks with bad Attribute values.
Tanks set out of service with inventory change between cases.
Meter ValidationMeters with corrected measurement.
Meters with zero measurement / tolerance.
Meters with zero density and non zero measurement.
Meters with change of in/out of service.
Meters density comparison to default density.
Meters density comparison between cases.
Meters measurement comparison between cases.
Meters with bad Attribute values.
Disconnected meters.
Gas Meters with zero molecular weight and non zero measurement.
Gas meters with molecular weight comparison between cases.
Node ValidationNodes with no inputs or outputs.
Nodes with change of in/out of service between cases.
Flow ValidationFlow without a valid source and/or destination.
Flows with change of in/out of service status between cases.
Flows without a material name specified.
Flows with change of material between cases.
Transfer ValidationTransfers with zero or missing values.
Transfers with negative measured values.
Transfers set to self calculate.
Transfers with bad Attribute values.
Analyzer ValidationAnalyzers with change of in/out of service.
Analyzers with bad Attribute values.
Disconnected analyzers.
Analyzer components with zero measurement/tolerance.
Analyzer component values below minimum or above maximum.
