MECHANICAL INSTALLATION
WARNING: REMOVE POWER FROM THE UNIT BEFORE INSTALLING, REMOVING, OR MAKING ADJUSTMENTS.
WARNING: INSTALLATION SHALL BE PERFORMED ONLY BY QUALIFIED PERSONNEL AND IN ACCORDANCE
WITH LOCAL GOVERNING REGULATIONS.
WARNING: MP SERIES AIR RADAR IS TO BE USED ONLY IN THE MANNER OUTLINED IN THIS MANUAL, OTHERWISE
PROTECTION PROVIDED BY THE DEVICE MAY BE IMPAIRED.
WARNING: NEVER ATTEMPT TO LOOSEN, REMOVE, OR DISASSEMBLE PROCESS CONNECTION OR INSTRUMENT
HOUSING WHILE VESSEL CONTENTS ARE UNDER PRESSURE.
WARNING: THE USER IS RESPONSIBLE FOR THE SELECTION OF BOLTING AND GASKET MATERIALS WHICH WILL
FALL WITHIN THE LIMITS OF THE FLANGE AND ITS INTENDED USE AND WHICH ARE SUITABLE FOR THE SERVICE
CONDITIONS.
WARNING: IMPROPER INSTALLATION MAY RESULT IN LOSS OF PROCESS PRESSURE.
WARNING: MP SERIES AIR RADAR LEVEL MEASUREMENT INSTRUMENT FALLS BELOW THE LIMITS OF ARTICLE 3,
SECTIONS 1&2 OF THE PRESSURE EQUIPMENT DIRECTIVE (PED, 97/23/EC), AS A CATEGORY I PRESSURE ACCESSORY.
HOWEVER, IN ACCORDANCE WITH PED, 97/23/EC, ARTICLE 3, SECTION 3, THIS EQUIPMENT HAS BEEN DESIGNATED
AND MANUFACTURED IN ACCORDANCE WITH SOUND ENGINEERING PRACTICE (SEP) (SEE EU COMMISSION
GUIDELINE 1/5).
GUIDELINES & CONSIDERATIONS
The following precautions should be observed when installing the MP Series air radar units:
•
Correct location is key to a successful application
•
Avoid reflective interference from vessel walls and obstructions by following the guidelines below.
•
Should not be mounted near the fill stream
BEAM
•
Beam angle is the width of the cone where the energy density is half of the peak energy density.
•
The peak energy density is directly in front of and in line with the antenna.
•
There is a signal transmitted outside the beam angle, therefore false targets may be detected.
•
Keep emission cone free of interference from ladders, pipes, I-beams or filling streams.
•
Avoid central locations on tall, narrow vessels
