Non-compliance can result in malfunctions or interference�
2 Safety instructions
• Please read the product description prior to set-up of the unit� Ensure that the
product is suitable for your application without any restrictions�
• The unit conforms to the relevant regulations and EC directives�
• Improper or non-intended use may lead to malfunctions of the unit or to unwan-
ted effects in your application�
• That is why installation, electrical connection, set-up, operation and mainte-
nance of the unit must only be carried out by qualified personnel authorised by
the machine operator�

3 Functions and features
3.1 Application area
The unit monitors the flow of liquid and gaseous media�
3.2 Operating principle flow monitoring
• The unit detects the flow speed to the calorimetric measuring principle and
switches the output:
- output closed if medium is flowing / output open if no medium is flowing�
This applies to the unit on delivery: output = normally open� In case of need you
can change the output to normally closed (→ 8�2)� It then applies: output open
if medium is flowing�
• If the flow speed increases, the switching status changes when the switch point
is reached�
• If the flow speed falls again, the switching status changes if the value "SP
minus hysteresis" is reached�
The hysteresis changes with the flow speed and it is essentially influenced by
the set monitoring range�
It is 2���5 cm/s for the setting 5���100 cm/s (= factory setting), it increases with
higher flow speeds�
• The typical response time of the unit is 1���10 s� It can be influenced by the
setting of the switch point:
- Low switch point = quick reaction with rising flow�
- High switch point = quick reaction with falling flow�
3.3 Communication (IO-Link)
• The unit is laid out for bidirectional communication� So, the following options
are possible:
- Remote evaluation (transmission of the process data)�
- Remote parameter setting (adjustment / output function)�
Device-specific parameter lists for IO-Link parameter setting are available at:
www�ifm�com → Select your country → Data sheet direct:

4 Installation
Using process adapters the unit can be adapted to different process connections�
• Adapters have to be ordered separately as accessories�
A correct fit of the unit and ingress resistance of the connection are only en-
sured using ifm adapters�
• For small flow rates ifm adapter blocks are available�
4.1 Installation location
General
• The sensor tip is to be completely
surrounded by the medium�
• Insertion depth of the sensor: minimum
12 mm�
Recommended
• For horizontal pipes: mounting from
the side�
• For vertical pipes: mounting in the rising
pipe�
Conditional
• Horizontal pipe /mounting from the bot-
tom: if the pipe is free from build-up�
• Horizontal pipe /mounting from the
top: if the pipe is completely filled with
medium�
To avoid
• The sensor tip must not be in contact
with the pipe wall�
• Do not mount in downpipes that are
open at the bottom!

4.2 Sources of interference in the pipe system
Components integrated in the pipes, bends, valves, reductions, etc� lead to turbu-
lence of the medium� This affects the function of the unit�
Recommendation: Adhere to the distances between sensor and sources of inter-
ference:
D = pipe diameter; S = sources of interference
4.3 Mounting operation
► Ensure that the system is free of pressure during installation�
► Ensure that no media can leak at the mounting location during installa-
tion�
► Grease the threads of the process connection (1), adapter (2) and nut (3)�
Note: The sensor tip (A) must not be in contact with grease�
► Screw the suitable adapter into the process connection�
► Place the flow monitor onto the adapter and tighten the nut� Tightening torque
25 Nm� Ensure that the unit is correctly oriented�

OUT1/Data
• OUT1 / Data = switching signal for flow limit value and data channel for bidirectional
communication
• Teach = input for teach signal
6 Operating and display elements
1: Operation display
• The green LEDs indicate the current flow (the LEDs 0 to 9 represent the range between
no flow and maximum flow)�
• A lighting LED indicates the position of the switch point (orange = output closed, red =
output open)�
2, 3: Setting buttons for adjustment and configuration

7 Set-up and settings for water
(For media other than water → 8�1: Low flow adjustment)�
► Switch on the supply voltage�
> All LEDs light and go out again step by step� During this time the output is
closed (if configured as normally open)� The unit is in the operating mode�
► Let the normal flow circulate in the installation�
► Check the display and determine further actions�
1
The factory setting is suitable for the appli-
cation�
► No further settings are required�
2
Your normal flow is below the representation
range of the display�
2 setting options:
► Change the switch point (→ 7�1)�
► Carry out high flow adjustment (→ 7�2)�
3
Your normal flow exceeds the representation
range of the display (LED 9 flashes)�
► Carry out high flow adjustment (→ 6�2)�
You can restore the factory setting any time� (→ 8�3)�
7.1 Change the switch point (optional)
For the factory setting the switch point is at LED 7� A change makes sense if:
• the display shows example 2�
• the flow fluctuates much or pulsates�
• if a faster response time of the unit is requested (low switch point = fast re-
sponse with rising flow, high switch point = fast response with falling flow)�
► Briefly press the pushbutton or �
> The switch point LED flashes�
► Press the pushbutton or as often as required� Each press of the push-
button shifts the LED by one position in the indicated direction�
Note: If no pushbutton is pressed for 2 s, the unit returns to the operating mode
with the newly set value�

UK
7.2 High flow adjustment (optional)
The unit determines the existing flow as normal flow and adapts the display repre-
sentation (all LEDs except the switch point LED light green)�
► Let the normal flow circulate in the installation�
► Press the pushbutton and keep it pressed�
> LED 9 lights, after approx� 5 s it flashes�
► Release the pushbutton�
The unit is now adapted to your flow conditions� It passes into the operating mode,
the display should now show example 1�
Note: The adjustment affects the switch point: It is increased proportionally (maxi-
mum up to LED 7)�
Remote adjustment → 8�5�
8 Additional settings (optional)
8.1 Low flow adjustment
If the unit is used in media other than water, you should additionally adapt the unit
to the minimum flow�
Note: The following adjustment must only be carried out after the high flow adjust-
ment�
► Let the minimum flow circulate in the installation or ensure flow standstill�
► Press the pushbutton and keep it pressed�
> LED 0 lights, after approx� 5 s it flashes�
► Release the pushbutton� The unit adopts the new value and passes into the
operating mode�
Remote adjustment → 8�5�
8.2 Configure the switching output
The unit is delivered as normally open� In case of need you can change the output
to normally closed:
► Press the pushbutton for at least 15 s�
> LED 0 lights, after approx� 5 s it flashes�
> After 10 s the current setting is displayed: LEDs 5���9 light orange (= output
normally open)�
> After approx� 15 s LEDs 0���4 flash orange�
► Release the pushbutton� The output is changed to normally closed operation�
For a new changeover repeat the operation�

8.3 Restore the factory setting (reset)
► Press the pushbutton for at least 15 s�
> LED 9 lights, after approx� 5 s it flashes�
> After approx� 15 s LEDs 0���9 flash orange�
► Release the pushbutton� All settings are reset to the factory setting:
- operating area: 5 ���100 cm/s for water
- switch point: LED 7
- output function: NO
- unlocked�
8.4 Lock / unlock the unit
The unit can be locked electronically to prevent unintentional settings�
► Press both setting pushbuttons simultaneously for at least 10 s in the operating
mode�
> The indication goes out, the unit locks or unlocks�
On delivery: unlocked�
8.5 Remote adjustment
You can adapt the unit to new flow conditions any time�
• Apply the operating voltage for > 5 ��� < 10 s to Pin 2 = high flow adjustment�
• Apply the operating voltage for > 10 ��� < 15 s to Pin 2 = low flow adjustment�
This adjustment does not affect the switch point (the relative position is not chan-
ged)�
9 Error during adjustment
If no adjustment is possible, all LEDs flash red� The unit then passes into the
operating mode with unchanged values�
Possible cause /aid:
Error during installation�
► Read chapter 4 Installation�
Check whether all requirements have
been met�
The difference between maximum flow and
minimum flow is too small�
► Increase the flow difference and carry
out the adjustment once again�
The sequence high flow /low flow adjust-
ment was not adhered to�
► Carry out the two adjustment operations
again in the right sequence�
