Delta Level calculation

The following example illustrates how to use TankMaster WinSetup to configure a Rosemount 2410 to
calculate the difference between product levels for two tanks Tank No. 1 and Tank No. 3. The result is
stored in tank measurement variable Delta_Level in Tank 1.
A Virtual Relay Output can be configured to use the measurement variable Delta_Level as source
parameter to trigger the relay whenever the level difference exceeds a specified value. See

Advanced Configuration
1. Choose subtraction.
2. Put the result in Tank Measurement Variable
TMV_Delta_Level.
3. Put the result in Tank 1.
Now the result will be stored in
TMV_Delta_Level for Tank 1.
4. For arithmetic operation parameter A
choose Tank Measurement Variable=Level.
5. Choose arithmetic operation parameter A
1
from Tank 1.

6. For arithmetic operation parameter B choose
3
Tank Measurement Variable=Level.
