5.3.3 Inventory Local Gravity and Ambient Air Density calculations are used for automatic
density measurements. To change the Inventory settings do the following:
1. Select the desired server (e.g. “This Workstation”) in the WinSetup
workspace.
2. Click the right mouse button and choose Setup, or from the Service
menu choose Servers>Setup.
3. In the Sever Preferences window select the Inventory tab:
4. Local Gravity.
The Local Gravity is used for density and weight calculations when an
optional pressure transmitter is installed.
Select Manual if you want to specify the Local Gravity.
Choose Calculated if you want the local gravity to be calculated by
TankMaster. In this case you need to enter the Latitude and Elevation of
the site.
5. Ambient Air Density.
The Ambient Air Density is used for calculating Observed Density and
Weight in Air (WIA).
Select Manual if you want to use a specific Ambient Air Density value.
Choose Calculated if you want the Ambient Air Density to be calculated
by TankMaster. The calculated value is based on the Base Density and
the Ambient Air Temperature.
See the TankMaster WinOpi Reference Manual (Document no.
303028EN) for more information on inventory parameters and
calculations.
