Flow measurement (FF configuration program) Cerabar S/Deltabar S/Deltapilot S FOUNDATION Fieldbus
36 Endress+Hauser
6.2 Totalizer
Example:
In this example, the volume flow should be totalized and displayed in the unit m
3
E
3
. Negative flows
should be added to the flow rate.
!
Note!
• For a description of the parameters mentioned, see
– → ä 82, DP Flow Transducer Block
– → ä 93, Analog Input Block.
• Totalizer 1 can be reset. Totalizer 2 cannot be reset.
!
Note!
• You can also specify a customer-specific unit. → See parameter descriptions for Totalizer 1 Unit/
TOTALIZER_1_UNIT (→ ä 86).
• You can use the Main Line Cont./DISPLAY_MAINLINE_CONTENT parameter (→ ä 88) to
specify which measured value should be displayed on the local operation.
• The parameters for the 2nd totalizer, such as Total 2. Eng. Unit/TOTALIZER_2_UNIT, Neg. Flow
Tot. 2/TOTALIZER_2_MODE and Totalizer 2/TOTALIZER_2_FLOAT can be found in the
Pressure Transducer Block.
Description
1 Calibrate the device in accordance with Section 6.1.
2 Open the DP Flow Transducer Block.
3 By means of the Totalizer 1 Unit/TOTALIZER_
1_UNIT parameter, select a flow unit, here m
3
E
3
for
example.
4 Use the Neg. Flow Tot. 1/TOTALIZER_
1_MODE parameter to specify the totalizing mode for
negative flows, here the "Positive" option for example.
5 Reset totalizer 1 to zero via the Resest Totalizer/
TOTALIZER_1_RESET parameter.
6Result:
The totalizer 1/TOTALIZER_1_VALUE parameter
displays the totalized volume flow.
