9.2.6 Linking input values to tank variables
Measured values must be linked to tank variables before they can be used in the Tank
Gauging application. This is done by defining the source of each tank variable in the
following parameters:
Tank variable Parameter defining the source of this variable
Product level • Setup → Level source
• Setup → Advanced setup → Application → Tank configuration → Level
→ Level source
Bottom water level Setup → Advanced setup → Application → Tank configuration → Level
→ Water level source
Average or spot temperature of the
product
• Setup → Liquid temp source
• Setup → Advanced setup → Application → Tank configuration
→ Temperature → Liquid temp source
Temperature of the air surrounding
the tank
Setup → Advanced setup → Application → Tank configuration
→ Temperature → Air temperature source
Temperature of the vapor above
the product
Setup → Advanced setup → Tank configuration → Temperature → Vapor
temp source
Density of the product Setup → Advanced setup → Application → Tank configuration → Density
→ Observed density source
Bottom pressure (P1) Setup → Advanced setup → Application → Tank configuration → Pressure
→ P1 (bottom) source
Middle pressure (P2) Setup → Advanced setup → Application → Tank configuration → Pressure
→ P2 (middle) source
Top pressure (P3) Setup → Advanced setup → Application → Tank configuration → Pressure
→ P3 (top) source
Depending on the application not all these parameters will be relevant in a given
situation.
