4. Installation
Piping connections and cable wiring for the LF150 detector are described in the following
sections.
4.1 Piping Connections
The LF150 detector has flanges on both ends of detector main body. To mount the LF150,
refer to Figure 4.1 and follow the procedure below:
1.
Place one of the flange packing next to the upstream(or downstream) pipe flange.
Align the holes of the packing with those of the flange so that the holes are not
obstructed.
2.
Insert the LF150 detector in pipeline in accordance with the flow direction arrow
on the detector.
IMPORTANT
A crane is needed to carry and install the detector.
3.
Insert the bolts, one at a time, through the hole in the upstream pipe flange and
packing, and then through the hole of the detector flange. Then thread nuts, one at a
time, on each end of the bolts, finger-tighten. This will help support the detector on one
side.
4.
Insert the downstream (or upstream) packing between the detector flange and the
downstream pipe flange. Align the holes of the packing with those of the flanges so that
the holes are not obstructed.
5.
Inert the bolts, one at a time, through the hole in the downstream pipe flange and
packing, and then through the hole of the detector flange. Then thread nuts, one at a
time, on each end of the bolts, finger-tighten. This will help support the detector.
6.
While centering the detector with the longitudinal axis of the pipeline, tighten the
bolts with a wrench diagonally across in even increments. Bolt torque should be limited
to that shown in Table 4.1
