Metal pipe with loose flanges

1. Solder the threaded nuts M6 (1) 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 (2) and an appropriate grounding point.

Plastic pipes, non-metallic pipes or pipes with insulating liner

For plastic pipes or pipes with insulating lining, the ground for the measuring agent is provided
by the grounding plate 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 plate is not
necessary.
1. Install the flowmeter sensor with grounding plate (3) in the pipeline.
2. Connect the terminal lug (2) for the grounding plate (3) and ground connection (1) on the
flowmeter sensor with the grounding strap.
3. Use a copper wire (min. 2.5 mm² (14 AWG)) to link the ground connection (1) to a suitable
grounding point.
