The signal quality of the sensor can be affected by irregularities in the medium (e.g. strong turbulences, air
bubbles, particles or build-up).
The unit detects the signal quality in three stages:
Signal quality Explanation Switching output
Normal
The device operates without restrictions (normal operation). On
Low
The signal quality is disturbed, but the device is still working within
its specifications.
OFF
No signal
No medium is present or no signal can be created. OFF
Parameters to be set:
oux = dOU; dFUx = signal quality
10.2.3 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 to-
taliser)
Acyclic
▪ The totalisers Vol.1 and Vol.2 can be reset. Totaliser Vol.L cannot be reset.
Totaliser reset [ 34].
▪ The totalisers Vol.1 and Vol.2 take account of the following parameter settings when totalising the
consumed quantity:
Flow direction [ 32].
Counting method of the totalisers [ 34].
Low flow cut-off [ 32].
▪ 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.
Read totaliser values [ 36]
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:
