• Conductivity: ≥ 20 µS/cm
• Viscosity: < 70 mm 2 /s at 40 °C; < 70 cST at 104 °F
5
4 Function
• The unit detects the flow based on the magnetic-inductive volumetric flow measuring principle�
• The unit also detects the medium temperature�
• It features an IO-Link interface�
• The unit displays the current process value�
4.1 Processing of the measured signals
The unit generates 2 output signals according to the parameter setting�
OUT1/IO-Link:
-Analogue signal for temperature
-Communication interface
OUT2:
-Analogue signal for volumetric flow quantity
Parameter setting
Parameter setting
4.2 Direction of flow
In addition to the flow velocity and the volumetric flow quantity, the unit also detects the direction of flow�
4.2.1 Determination of the direction of flow (Fdir)
An arrow with the text "flow direction" on the unit indicates the positive flow direc-
tion� The flow direction can be inversed (→ 10.4.4)�
► Use the supplied label to mark the changed flow direction (new positive direction of flow)�
Flow...
corresponds to the marked flow direction against the marked flow direction
Process value display
+ (positive)
- (negative)
4.3 Consumed quantity meter
The unit has an internal mass flow meter which continuously totals the volumetric flow quantity� The total corresponds to the current consumed quantity�
• The quantity meter takes account of the flow direction for totalisation:
6
-Flow according to the marked flow direction (arrow "flow direction"): meter adds�
-Flow against the marked flow direction: meter subtracts�
The meter saves the totalled consumed quantity every 10 minutes� After a power failure this value is available as the current meter reading� So the possible data loss can be maximum 10 minutes�
The current meter reading can be evaluated via an external parameter setting
software (→ 10.5.5 Activating the IO-Link communication interface)�
4.4 Empty pipe detection
The unit detects when the two electrodes are not wetted by the medium� The
empty pipe detection can be activated or deactivated (→ 10.4.7)� If it is active and
the pipe is empty, the unit reacts as follows:
UK
> [SEnS] is indicated in the display�
> The flow is set to zero�
The empty pipe detection can be set as time-depending or not time depending (→
4.5 Analogue function
• The unit provides an analogue signal that is proportional to the volumetric flow quantity and the medium temperature�
• Within the measuring range the analogue signal is 4���20 mA�
• If the measured value is outside the measuring range or in the event of an internal error, the current signals indicated in Figure 1 are provided�
• The measuring range is scalable:
[ASP] determines at which measured value the output signal is 4 mA�
[AEP] determines at which measured value the output signal is 20 mA �
Minimum distance between [ASP] and [AEP] = 20 % of the final value of the measuring range�

4.6 Measured value damping (dAP)
The damping time allows to set after how many seconds the output signal has reached 63 % of the final value if the flow value changes suddenly� The set damping time stabilises the outputs, the display and the process value transfer via the
IO-Link interface� The signals [UL] and [OL] (→ 12 Troubleshooting) are defined
under consideration of the damping time�
UK
4.7 Low flow cut-off (LFC)
With the function Low Flow cut-off small volumetric flow quantities can be ignored
(→ 10.4.10)� Flows below the LFC value are evaluated by the sensor as standstill
(Q = 0)�
