INSTALLATION
The Special Conditions for Safe Use detailed in section 9 ATEX APPENDIX must be observed
and followed at all times.
In order to effectively install and calibrate the unit to a particular pipeline the pipeline should
be filled with an acoustically transparent fluid at the time of installation (single phase, no gas
bubbles, no large solid particles).
Because the transducer is permanently connected to the main housing via a cable and the
transducer is screwed into contact with the pipeline some precautions must be taken to avoid
the cable becoming excessively twisted. The figure below shows the preferred mounting
positions for the system.
4.1.
MAIN HOUSING INSTALLATION
1.
Referring to the figure above fit the main housing mounting plate onto the main housing
mounting block with 4xM8x35 CAP screws and washers.
2.
Fit the main housing onto the mounting plate with 2xM8x25 CAP screws, washers, and
NYLOC nuts.
3.
With the help of another person sit the main housing assembly on the pipeline at a
suitable location and using the provided straps securely tighten the assembly onto the
pipeline.
4.
Connect the earth stud on top of the main housing to a suitable earth bonding point at the
point of installation.
