1
Solder the threaded nuts M6 to the pipeline and connect
the ground as shown in the illustration.
2
Use a copper wire (at least 2.5 mm2 (14 AWG)) to
establish the ground connection between the sensor and
an appropriate grounding point.
For plastic pipes or pipes with insulating lining, the grounding
for the measuring medium is provided by the grounding ring
as shown in the figure below or via grounding electrodes that
must be installed in the device (option). If grounding
electrodes are used, the grounding ring is not necessary.
1
Install the flowmeter sensor with grounding ring in the
pipeline.
2
Connect the terminal lug for the grounding ring and
ground connection on the flowmeter sensor with the
grounding strap.
3
Use a copper wire (min. 2.5 mm² (14 AWG)) to link the
ground connection to a suitable grounding point.
Grounding for devices with protective plates
The protective plates are used to protect the edges of the
liner in the meter tube, e.g., for abrasive fluids. In addition,
they function as a grounding ring.
• For plastic or pipes with insulating lining, electrically
connect the protective plate in the same manner as a
grounding ring.
