9.2.3 Consumed quantity monitoring (totaliser function)
The unit has 3 internal quantity meters (totalisers Vol.1, Vol.2 and Vol.L). The totalisers continuously
sum up the consumed quantity and provide this process value via the IO-Link interface.
Totaliser Process value Read access via IO-Link
Vol.1 Consumed quantity 1
(This value is used for consumed quantity monitoring by
switching or pulse signals)
Cyclic
Vol.2 Consumed quantity 2 Acyclic
Vol.L Consumed quantity over the whole lifetime (lifetime totalis-
er)
Acyclic
• The totalisers Vol.1 and Vol.2 can be reset. Totaliser Vol.L cannot be reset.
Ò Totaliser reset (Ò/28).
• The totalisers Vol.1 and Vol.2 take account of the following parameter settings when totalising the
consumed quantity:
Ò Flow direction (Ò/27).
Ò Counting method of the totalisers (Ò/29).
Ò Low flow cut-off (Ò/27).
• The Life Time Totalisator Vol.L totals all flow quantities regardless of the flow direction and
counting method.
• When the detection range (cr.OL) is exceeded, the totalisers use the last valid flow rate value
(measuring range end value) and continue counting with this value.
• In addition to the current consumed quantity, the value before the last reset is saved. This value
and the time since the last reset can also be displayed.
Ò Read totaliser values (Ò/31)
The totaliser saves the totalled consumed quantity at regular intervals. After a power failure this
value is available as the current meter reading. If a time-controlled reset is set, the elapsed time
of the set reset interval is also saved. This means that the possible data loss can amount to one
minute.
• The accuracy of the consumed quantity measurement depends on the accuracy of the flow
measurement.
• A switching signal or pulse signals can be provided for consumed quantity monitoring:
Ò Switching signal totaliser (Ò/21)
Ò Pulse signal totaliser (Ò/22)
OUT1 and OUT2 cannot be used simultaneously for the consumed quantity monitoring.
9.2.3.1 Switching signal totaliser
A switching signal can be provided for consumed quantity monitoring.
When totaliser Vol.1 has totalled the flow quantity (pulse value) set under [ImPS], the output provides
a switching signal.
The flow rate depends on the counting method of the totalisers: Depending on the setting of the [FPro]
parameter, the direction of flow is taken into account in different ways when totalling the flow rate.
Ò Counting method of the totalisers (Ò/29).
The output remains switched until a totaliser reset is carried out. When the totaliser has been reset,
metering starts again.
The totaliser is reset automatically or manually.
