C.8.1 Delta Level Calculation

Figure C-13. Arithmetic operations are configured in Holding Registers 4800 to 4879

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 1 and Tank 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 “Relay Output” on page C-6for more information on how to configure relay functions for a Rosemount 2410.

 

1.

Choose subtraction.
