Azbil Corporation  Installation
MagneW FLEX+/PLUS+ Electromagnetic Flowmeter Detector  2-9
2.4.3: Necessary parts
You will need the following parts to install a wafer detector:
•  Centering nuts (four supplied)
•  Connecting bolts and nuts (available separately)
•  Gaskets: Required when using grounding rings made of SUS material. Not 
required when using grounding rings made of hastelloy, titanium, tantalum, or 
platinum.
•  Protective Plate: Required when connecting the detector to polyvinyl chloride 
(PVC) piping.
Centering nuts
The centering nuts create the exact alignment of the pipe and detector. These nuts 
are positioned on through-bolts and the detector is set on top of the nuts to properly 
position it against the anges.
The position of the centering nuts depends on the direction in which the detector is 
installed. For horizontal centering of the detector, position two centering nuts against 
each ange. For vertical centering of the detector, position the four centering nuts on 
the bottom ange. The following gures show horizontal and vertical centering nut 
positions.
