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 1.2.1
”Orientation of flow sensor electronics box”,
page 9)

(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 1.2.1
”Orientation of flow sensor electronics box”, page 9)
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 Figure 6.
If ULTRAFLOW® 54 is mounted horizontally the electronics box can be mounted on
the distance piece by means of the collar band. The distance piece can then be
turned upwards until the cable connections on the electronics box are in a higher
position than the cable connection on the flow sensor housing. See Figure 7.
Alternatively, the electronics box can be wall mounted at a suitable distance to the
installation (minimum 170 mm).
