1.1.3 Installation of process
couplings and deflectors
SMART-PULP LL/LS/GL/RL/HL
Using the welding guide shown in Fig.
1.1.3f, you weld the process coupling
exactly at right angles (90
pipe as shown in Fig. 1.1.3a. (Welding
instructions are supplied in the kit. Also
refer to Fig. 1.1.2c).
Procedure:
- Make a Ø71 mm hole in the pipe.
- Attach the process coupling to the
welding guide.
- Equalize the height adjustment at both
ends of the guide to ensure that the
guide is supported steadily on its end
pieces and will not rock on the coupling.
- Attach the welding guide to the process
pipe with mounting straps.
- Weld the coupling at 4 points on the
pipe.
- Remove the guide and complete the
welding.
Deflector distances L3 and L4 for types
LL/LS/GL/RL: L3 = L4 = 300 mm; and for
type HL: L3 = L4 = 150 mm.
The deflector downstream from the
sensor is only installed in applications
with a risk of back flow that might
damage the sensor (e.g. when stopping
or starting the process). The deflectors
must be centered exactly in line with the
process coupling. The deflectors have
Ø5 mm holes to facilitate installation; for
instance, you may insert a piece of wire
through the holes. In exceptional cases,
when process pressure exceeds 10 bar
and/or there is exceptionally strong
vibartion, it is advisable to reinforce the
mounting of the process coupling with a
reinforcing ring (Fig. 1.1.3b). Deflector's
inlet to the pipe should also be reinforced
in the same way.
SMART-PULP UL
Installation in bypass line (Fig. 1.1.2e):
Install the process coupling as described
above, but exclude the deflectors. When
installing in the actual process line you
may require an installation tube (Fig.
1.1.2b) without deflectors.

Install the process coupling as shown in Figure 1.1.3c. Cut a 9
mm by 182 mm bevelled hole for the deflector on the pipe.
Place the coupling on the pipe and draw the outline of the
coupling's bore on the pipe. Then cut out the mounting hole.
Remove all burrs from the hole, and round the edges of the
hole. Weld the coupling. Install the backflow deflector in line
with the coupling's center line
