Totalizers
Example:
In this example, the volume flow should be totalised 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
– Page 107 ff, Table 18: TOTALIZER SETUP
– Page 123 ff, Table 29: PROCESS VALUES
• Totalizer 1 can be reset. Totalizer 2 cannot be reset.
!
Note!
• You can also specify a customer-specific unit.
See parameter description for TOTALIZER 1
UNIT (
Page 108) and TOTALIZER 2 UNIT (
• The TOTALIZER 1 and TOTAL. 1 OVERFLOW parameters display the totalised flow value of the
first totalizer. The TOTALIZER 2 and TOTAL. 2 OVERFLOW parameters display the totalised
flow value of the second totalizer.
See Page 123 ff, PROCESS VALUES function group.
• You can use the MENU DESCRIPTOR parameter (
Page 110) to specify which measured value
should be displayed on the on-site display.
Description
1
Calibrate the device as per Section 6.1.

3
Select a flow unit via the TOTALIZER 1 UNIT
parameter, here m

E
3
for example.
4
Use the NEG. FLOW TOT. 1 parameter to specify the
totalising mode for negative flows, here the "Positive"
option for example.
5
Reset totalizer 1 to zero via the RESET TOTALIZER
parameter.

Result:
The TOTALIZER 1 and TOTAL. 1 OVERFLOW
parameters display the totalised volume flow.
