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 Validation | Analysis Rule |
|---|---|
| Tank Validation | Tanks 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 Validation | Meters 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 Validation | Nodes with no inputs or outputs. |
| Nodes with change of in/out of service between cases. | |
| Flow Validation | Flow 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 Validation | Transfers with zero or missing values. |
| Transfers with negative measured values. | |
| Transfers set to self calculate. | |
| Transfers with bad Attribute values. | |
| Analyzer Validation | Analyzers 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. |
