5.4.3 Metal pipe with loose flanges
Fig. 26: Metal pipe, without liner (example)
A Flange design B Wafer-type design
1 Threaded nuts M6 2 Ground terminal
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 mm
2
(14 AWG)) to
establish the ground connection between the sensor and
an appropriate grounding point.
5.4.4 Plastic pipes, non-metallic pipes or pipes with
insulating liner

liner
A Flange design B Wafer-type design
1 Earth connection 2 Terminal lug 3 Grounding ring
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.
5.4.5 Sensor type HygienicMaster
Fig. 28
1 Process connection adapter
Ground the stainless steel model as shown in the figure. The
measuring fluid is grounded via the process connection
adapter and an additional ground is not required.
5.4.6 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.
5.4.7 Grounding with conductive PTFE grounding plate
For devices with a meter size between DN 10 … 250,
grounding rings made of conductive PTFE are available. These
are installed in a similar way to conventional grounding ring.
