4 Function
• The unit detects the flow based on the magnetic-inductive volumetric flow
measuring principle�
• The unit also detects the medium temperature�
• The unit displays the current process value�
4.1 Processing of the measured signals
The unit generates 2 output signals according to the parameter settings:
OUT1:Parameter setting
UK
- Analogue signal for temperature→ 10.2
OUT2: Parameter setting
- Analogue signal for volumetric flow quantity→ 10.3
4.2 Direction of flow
In addition to the flow velocity and the volumetric flow quantity, the unit also
detects the direction of flow�
An arrow with the text "flow direction" on the unit indicates the positive flow
direction�
Flow...Process value display
corresponds to the marked flow direction+ (positive)
against the marked flow direction- (negative)
Only positive process values are processed for the signal output�
5
4.3
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�

CAUTION
If the medium temperature is above 50 °C (122 °F) parts of the housing can
increase in temperature to over 65 °C (149 °F)�
>Risk of burns�
► Protect the housing against contact with flammable substances and
unintentional contact�

valves, reductions, etc� are compensated for� It applies in particular: no shut-off
and control devices are allowed directly in front of the unit�

5.4 Installation in pipes
The units with a G thread can be installed in the pipes using adapters�
Information about the available mounting accessories at www�ifm�com�
A correct fit of the unit and ingress resistance of the connection are only ensured
using ifm adapters�
AADDCCBB
UK
1� Grease the threads of the process connection, adapter and sensor� Use a
lubricating paste which is suitable and approved for the application�
2� Screw the adapter (B) into the pipe (A)�
3� Place the seals (C) and install the unit according to the marked flow direction�
4� Screw the adapter (B) with the threads (D) until it is hand-tight�
5� Tighten the two adapters in opposite direction (Tightening torque: 30 Nm)�
After installation air bubbles in the system can affect the measurement�
► Corrective measures: Rinse the system after installation for ventilation�
In case of horizontal installation:
As a result of design requirements a small quantity of the medium always
remains in the measuring channel after switching off the pump�
