Mounting of ULTRAFLOW
®
54 electronics box
At
medium temperature below 90°C (T
med
< 90°C) and at medium temperature less than
5°C below ambient temperature (T
med
> T
amb
- 5°C)
the electronics box can be mounted
directly on the flow sensor housing via the factory mounted fitting.
If the flow sensor is vertically mounted, the cable connections of the electronics box will
be horizontally oriented. This is permitted. If the cable connections should preferably
point downwards, the electronics box can be mounted via the enclosed distance piece,
which moves the box approx. 170 mm away from the flow sensor housing. Alternatively,
a shorter distance piece, which only moves the box approx. 45 mm away from the flow
sensor housing, can be used. The short distance piece must be ordered separately
(6561-332).
At
medium temperature above 90°C (T
med
> 90°C)
the temperature is too high for the
electronics box to be mounted directly on the flow sensor housing.
Therefore, the electronics box must be mounted via the enclosed distance piece. The
cable connections must always point downwards. (See
paragraph 7.2.1
)
Alternatively, the electronics box can be wall mounted as long as the distance to flow
sensor housing and pipe installation is minimum 170 mm.
It can also be an advantage to use the enclosed distance piece if the flow sensor
housing is insulated and the electronics box must be removed from the insulation.
If the required position of the electronics box differs from standard position, the
distance piece can be mounted with the enclosed collar band around the flow sensor
housing. However, please note that the cable connections must always point
downwards. (See
paragraph 7.2.1
)
At
medium temperature more than 5°C below ambient temperature (T
med
< T
amb
- 5°C)
(typically in cooling installations) it is important to take action to avoid condensation
in the electronics box.
Therefore, the electronics box must be mounted via the enclosed distance piece.
The cable connections must always point downwards. (See
paragraph 7.2.1
).
Alternatively, the electronics box can be wall mounted as long as the distance to flow sensor housing and pipe
installation is minimum 170 mm.
Furthermore, when mounting the electronics box please make sure that the cable connections on the box are at a
higher level than the cable connection on the flow sensor housing.
By vertical mounting of ULTRAFLOW
®
54 in a riser this can be secured by mounting the distance piece by means of
the collar band as shown in
