V = volumetric flow quantity, Imp = output pulses
• The current meter reading can be displayed (→ 11.1 Reading the process
• In addition the value before the last reset is stored� This value can also be
displayed (→ 11.1 Reading the process value).
The meter saves the totalled consumed quantity every 10 minutes�
In the event of a power failure this value is retained as the current meter
reading� If a time-controlled reset is set, the elapsed time of the set
reset interval is also stored� So the possible data loss can be maximum
10 minutes�
There are different ways to reset the meter
→ 10.4.4 Manual counter reset
→ 10.4.5 Time-controlled counter-reset
→ 10.4.7 Configure counter reset using an external signal
4.4.1 Consumed quantity monitoring with pulse output
Output 1 indicates a counting pulse when the set volumetric flow quantity has
been reached (→ 10.4.1).
4.4.2 Consumed quantity monitoring with preset counter
Output 1 switches when the set volumetric flow quantity has been reached (→
2 types of monitoring are possible:
1� Time-dependent quantity monitoring (→ 10.4.5 Time-controlled counter-reset).
-If the quantity x is reached during t, output 1 switches and remains switched
until the meter is reset�
