1 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�
• Improper or non-intended use may lead to malfunctions of the unit or to un-
wanted 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�

2 Functions and features
2.1 Application area
The unit monitors the flow of liquid and gaseous media�
2.2 Operating principle flow monitoring
• The unit detects the flow speed to the calorimetric measuring principle and
switchestheoutput:
- output closed if medium is flowing / output open if no medium is flowing�
Thisappliestotheunitondelivery:output=normallyopen.Incaseofneedyou
canchangetheoutputtonormallyclosed(→7.2).Itthenapplies:outputopen
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�
Itis2...5cm/sforthesetting5...100cm/s(=factorysetting),itincreaseswith
higher flow speeds�
• The typical response time of the unit is 1���10 s� It can be influenced by the
settingoftheswitchpoint:
- Lowswitchpoint=quickreactionwithrisingflow.
- Highswitchpoint=quickreactionwithfallingflow.

3 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
ensuredusingifmadapters.Mountingoftheadapter→3.3.
3.1 Installation location
General
•The sensor tip is to be completely
surrounded by the medium�
•Insertiondepthofthesensor:
minimum 12 mm�
Recommended
•Forhorizontalpipes:mountingfrom
the side�
•Forverticalpipes:mountinginthe
rising pipe�
Conditional
•Horizontal pipe /mounting from
thebottom:ifthepipeisfreefrom
build-up�
•Horizontal pipe /mounting from the
top:ifthepipeiscompletelyfilled
with medium�
To avoid
•The sensor tip must not be in
contact with the pipe wall�
•Donotmountindownpipesthatare
open at the bottom!

3.2 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:Adheretothedistancesbetweensensorandsourcesof
interference:
D=pipediameter;S=sourcesofinterference
3.3. Mounting operation
►Ensure that the system is free of pressure during installation�
►Ensure that no media can leak at the mounting location during installation�
G:grease

UK
► Mounttheadapter(D)ontheunit(A).
►Fix the unit + adapter to the process connection by means of a coupling nut, a
clamp flange or the like (B)�
Ifitisnotpossibletoslidethefixingelement(B)downoverthetopoftheunit:
Slide it up over the bottom of the sensor before the adapter is mounted�
Mounting the adapter
►Slightly grease the threads and sealing areas of the sensor and adapter with
lubricating paste�
The paste must be suitable and approved for the application and compatible
with the elastomers used�
Recommendation:KlüberpasteUH184-201withUSDA-H1approvalforthe
food industry�
►Make sure that the O-ring (C) is correctly positioned�
►Screw the unit into the adapter until it is hand-tight� Avoid mechanical influence
on the sealing areas�
►Clamp unit and adapter into a clamping device (E)� The sealing areas (F) must
not be damaged�
►Tighten the unit slightly using a spanner until you can feel the end stop (this
correspondstoamaximumtighteningtorqueof25Nm).NOTE:Furthertight-
ening may affect the sealing effect
NOTE:Aguaranteeforlong-termstableandmaintenance-freefittingwithnobug
traps in the hygienic sealing of the metal seal (Aseptoflex connection) is only valid
for once-only mounting�
Mounting by means of a welding adapter
►Weld adapter in the pipe or the tank�
►After the unit has cooled down insert and tighten it� Follow the instructions
included with the adapter�

4 Electrical connection
The unit must be connected by a qualified electrician�
The national and international regulations for the installation of electrical
equipment must be adhered to�
Voltage supply to EN 50178, SELV, PELV�
► Disconnectpower.

7 Additional settings (optional)
7.1 Low flow adjustment
If the unit is used in media other than water, you should additionally adapt the unit
to the minimum flow�
Note:Thefollowingadjustmentmustonlybecarriedoutafterthehighflowadjust-

operating mode�
7.2 Configure the switching output
The unit is delivered as normally open� In case of need you can change the output
