4.8.3 Metal pipe with loose flanges
1.
Solder the threaded nuts (2) M6 to the pipeline.
2. Insert M6x12 threads (3) in the flanges for the flowmeter sensor.
3.
Secure the ground straps (1) with nut, spring washer, and shim as shown in the figure, and
connect to the flowmeter sensor with ground connection (3).
4.
Use a copper wire (minimum 2.5 mm² (14 AWG)) to establish a connection between the
ground connection (3) and an appropriate grounding point.

4.8.4 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 (1) in the pipeline.
2.
Insert M6x12 threads (2) in the flange for the flowmeter sensor.
3.
Connect the terminal lug for the grounding plate (3) and the ground connection on the
flowmeter sensor (2) with the grounding strap.
4.
Use a copper wire (minimum 2.5 mm² (14 AWG)) to establish a connection between the
ground connection (2) and a good grounding point.
