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

For plastic pipes or pipes with insulating lining, the earthing for the measuring medium 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 earthing terminal (1) to a suitable
earthing point.
