4.2.2 Installation Procedure
To mouiu thu LF434/J.F404, plai:c il between Itic upstream and downstream pipe flanges
and tighten it with flange holts and nuts. See f igure 4,2 t Tablc4,1 and follow ihe
procedure below:
1. Place one of the flange packing next to the upstream (or downstream) pipe llattge. Altgi^
the holes of the packing with those of the flange so that the holes arc not obstructed.
2, Insert the Lh’434 detector in pipeline in accordance with the flow direction arrow on the
detector.
3, Insert the bolts, one at a time, through the hole in the upstream (or 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
on one side.
4, Insert the downstream (or upstream) packing between the detector flange and the down­
stream (or upstream) pipe flange. Align the holes of the packing with those of tlie flanges
so that the holes are not obstructed.
5. Inert the bolts, one at a time, through the hole in the downstream (or upstream) pipe
flange and packing, and tJien through the hole of the detector flange. Then thread nuts,
one at a time, on each end of the holts, finger-tighten. This will help support the detector.
6. While centering Ihe detector with ihe longitudinal axis of the pipeline, tighten the bolts
with a wrench diagonally across in even increrr^nis______________________________
IMPORTANr
When high-temperuiure fluid is being measured, radiant heal from the detector pipe surface
and adjoining pipes may cause the ambient temperature of the converter to go above 6t)
If the ambient lemperature goes above 60° C, try to lower the temperature by measures such
as wrapping heat-insulating materials over the detector pipe and adjoining pipes.
