Azbil MagneW FLEX+ - Figure 2-29 Installation on a PVC Pipe Using SUS Grounding Ring Material with Rubber Gaskets (Not Recommended)

Installation Azbil Corporation
2-38 MagneW FLEX+/PLUS+ Electromagnetic Flowmeter Detector
To install a anged detector on a PVC pipe using SUS grounding ring material
with rubber gaskets and a low fastening torque:
CAUTION
The use of rubber gaskets and a lower fastening torque is not recommended and
can cause insucient surface pressure between the lining and the grounding ring,
resulting in leakage.
(1) Remove the grounding ring from the detector and insert a rubber gasket 0.5 to 1.0
mm (0.02 to 0.04 inch) thick between the lining and the grounding ring.
(2) Reinsert the grounding ring on top of the rubber gasket.
(3) Remove the PTFE gasket and insert a rubber gasket 3.0 to 4.0 mm (0.12 to 0.16
inch) to replace it.
(4) With the rubber gaskets in the position shown in the following gure, attach the
detector to the pipe. Both rubber gaskets should be made of the same material.
