Warning
risk of injury due to non-conforming commissioning.
Non-conforming commissioning may lead to injuries and
damage the device and its surroundings.
• Before commissioning, make sure that the staff in
charge have read and fully understood the contents of
the manual.
• In particular, observe the safety recommendations and
intended use.
• The device / the installation must only be commis-
sioned by suitably trained staff.
note
risk of damage to the device due to the environment
• Protect this device against electromagnetic interfer-
ence, ultraviolet rays and, when installed outdoors, the
effects of the climatic conditions.
To make sure the device operates correctly, plug in
and tighten the connector.

Fluid velocity
installation of the fitting onto the
pipe
Choose a fitting appropriate to the velocity and the
flow rate of the fluid inside the pipe, refer to the graphs
at right (see Tab. 3). The graph is used to determine
the DN of the pipe and the fitting appropriate to the
application, according to the fluid velocity and the flow
rate.
Install the fitting on the pipe as described in the oper-
ating instructions of the fitting used.
Example:
• Specification:
- nominal flow: 10 m
3
/h,
- optimal flow velocity: between 2 and 3 m/s
• Solution: intersection between flow rate and flow velocity
in the graph gives the appropriate pipe diameter, DN40
(or DN50 for the asterisked fittings).
* For the fittings:
• with external thread connections acc. to SMS 1145,
• with welding end connections acc. to SMS 3008,
BS 4825 / ASME BPE or DIN 11850 Rg 2,
• Clamp connections acc. to SMS 3017/ ISO 2852, BS
4825 / ASME BPE or DIN 32676
The device cannot be installed on the DN20 fittings listed
1)
above.
