. Emerson Automation Solutions/Rosemount Tank Gauging
may in some cases recommend even more temperature elements for Custody Transfer tanks, depending
on how the tanks are operated.
Figure 3-3. Recommended position of temperature elements for Custody Transfer applications
Table 3-1. Number of spot sensors for various tube lengths
Example
5 spot sensors and H=10 m.
A=10/(5-1)=2.5 m.
The position of a temperature element is measured from the Tank Zero Level. See the
Gauging System Configuration Manual
for more information about how to use the TankMaster WinSetup
software to configure temperature elements for average temperature calculations.
