A Thickness Measurement is a value that quantifies the thickness of a given TML at a specific point in time.
Each TML will have various types of Thickness Measurements, including:
- Base Measurement: The first measurement taken for the TML.
- Near Measurement: The second-most-recently-recorded measurement for the TML.
- Last Measurement: The most-recently-recorded measurement for the TML.
Base, Near and Last Measurements are not recorded in the Thickness Measurements themselves. Instead, they are determined for the TML Corrosion Analysis by evaluating how many Thickness Measurements exist, and when the Thickness Measurements were created. After you create a new TML, you will want to record the base measurement, which represents the first recorded reading for that TML. Additional Thickness Measurements will be created later, as measurement readings are taken throughout the life of the asset.
IMPORTANT: To ensure data integrity, existing Thickness Measurements should be managed using Thickness Monitoring instead of the Record Manager.
