4.4 Mounting of MULTICAL® 403 calculator
4.4.1 Compact mounting
Compact mounting means that the calculator is
mounted directly on the flow sensor. If there is risk
of condensation (e.g. in cooling
applications), the
calculator ought to be wall mounted. Furthermore,
MULTICAL

403 in cooling applications must be the
condensation-proof version, type 403-T/C.
The construction of MULTICAL

403 can provide
minimum installation depth, both at 45° and 90°
mounting of the flow sensor. Due to the design the
mounting radius remains 60 mm in critical places.
4.4.2 Wall mounting
The calculator can be mounted directly on an even
wall. Wall mounting requires a wall fitting (3026-
655), which is available as an
accessory to
MULTICAL

403. MULTICAL

403 is mounted on the
wall fitting by sliding the calculator onto the fitting in
the same way as it is done by compact mounting.
Note:
Regarding qp 3,5 and bigger flow sensors the
fitting on the flow sensor can be dismounted and
used as a wall bracket.
4.4.3 Position of calculator
If the flow sensor is installed in humid or condensing
environment, the calculator must be wall mounted
and positioned higher than the flow sensor.
